About phase and amplitude after filtering

Sir please give me solution to this
i have a signal with phase,frequency n amplitude. To this signal i have added noise and i filtered that signal
after filtering the amplitude and phase are reducing
how can i get exact values of phase and amplitude after filtering
if i change frequency, ampliteude or phase it should give exact results after filtering........
plz solve this one for me................

Hi upto my knowledge the mistake you made is the cut-off frequency.. your input signal is only 10Hz so you try setting it as the cutoff freq. Try this...
The best solution is the one you find it by yourself

How to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++?

Hi,
I wonder if anybody know how to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++? This is a part of my project: I need to dynamically generate a sine wave voltage signal by some calculation using the data from a simultaneous analog input and another signal.
Your help will be appreciated so much!

Hello Marlon,
Here is an example of changing frequency and ampliude for an E-series device in Labwindows/CVI. The programming should be similar in C for your S-Series device. As is says on the linked webpage above, this process is going to be very processor intensive since you will continually be creating a buffer.

Firefox will open 4 or 5 tabs fine, but then will not load any further websites after those first 4 or 5, or allow you to refresh one of those first tabs -- including about:config and the addon page

Firefox 5 worked fine. I installed Firefox 7, and when I ran it, tabs would just say "connecting to..." and hang. Restarting did not help. Websites open fine in IE and Chrome. Disabled all firewalls and antivirus, did not help. Uninstalled and reinstalled Firefox 5, everything worked fine again. This was using Vista 64-bit.
Upgraded to Windows 7, uninstalled Firefox 5, installed Firefox 7, had same problem. Uninstalled Firefox 7 completely (including the profile information, I saved that information in another folder), restarted computer, and installed Firefox 7 using a completely clean profile. Did not install any add-ons, checked to make sure all plug-ins were up-to-date, and updated plugins.
Now when I start Firefox, I can load 3 or 4 or 5 tabs fine -- after those first few tabs are open, I cannot open or refresh any other tabs -- including about:config and the add-on manager -- I have to restart Firefox. The hangup doesn't appear to be related to what websites I am attempting to open, but it looks like the number is the problem. I have run through all of the FAQ procedures, including changing the max number of network connections to 48, and the problem does not seem to go away.
As a side note, I had this same problem when I tried to go from version 5 to version 6 as well. Version 5 is the most recent version that worked on my system.

Can you try Aurora - download it from http://www.mozilla.org/en-US/firefox/channel/

Many thanks.
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

My iPhone is about 6 months old now and I would say I don't use it that much. Yet for the last month or so the battery life has been going down and today after having charged it to 100% this morning, it was at 5% at 4 pm this aft. help!!

Ok Fellas, let me give you a clue: Games, particularly those that make heavy use of graphics and sound are notoriously power hungry. In fact, when I was in the Navy many years ago, the folks working on the NTDS (Navy Tactical Data System) computers used a version of Space Invaders to load test the AN/UYK-43 computers.
I have also noticed that all of my laptops (I have a brand new Toshiba dual core, an older Toshiba single core, plus 2 Dell dual core machines) have significantly shorter battery life when I play Company of Heroes than when I am just reading e-mail or surfing the 'Net. I have also noticed the same behavior when I play games on my 4th gen Touch and my iPhone 4.
The fact is, iOS 5 did make some major improvements as well as adding some nice functionality like iMessage, wireless synch, and such, but the down side is that depending on how you use the device battery life can be shorter that what you may have experienced with pervious versions of iOS. Its just the nature of the beast...

Updated document about QuickTime errors with After Effects (re: H.264 and hyperthreading)

I just updated "troubleshooting QuickTime errors with After Effects CS5, CS5.5, and CS6" with information about hyperthreading and Apple's H.264 encoder.
The gist is that Apple's H.264 exporter component for QuickTime fails when the computer has a large number of CPUs.

No, this applies to any QuickTime H.264 export. You can export H.264 in a QuickTime .mov wrapper out of AME, too, and it will have this problem.
The various H.264 encoding presets (for YouTube, Blu-ray, Vimeo, iPad, etc.) don't use the H.264 QuickTime component, so this isn't relevant to them.
This problem is just relevant to choosing Apple's H.264 as the video codec when choosing QuickTime as a format. This applies to all software that uses QuickTime, by the way, not just Adobe software.

Unable to get Zero Phase shift after filtering PWM

Hi,
After filtering the PWM signal i'm not getting the exact shape of Sine wave, i'm using the Zerophaseshiftfilter.vi in the blockdiagram.I've also attached the resulting waveforms that i'm getting. Anybody help me out.
Thanks

PWM- Sine.bmp ‏486 KB

sayaf,
Thanks for including the image -- it's a big help. Now I'm not the greatest expert at filtering, but to my eye you're getting a pretty reasonable approximation. I don't know how much better you can get when you only have about 8 PWM cycles for defining a half-cycle of the sine wave you want to see. At least, it looks pretty good if you have to handle a very general case of modulation.
Can the modulation always be considered a pure sine wave with a constant frequency throughout your sampling time? If so, then you can use that knowledge to your advantage -- for example, pass a few cycles of your filtered signal into one of the tone-extraction vi's that ship with LabVIEW. I'm sure there are other good (probably better) methods as well.

Lost all my actions and 3rd party filters after upgrading to Photoshop CC 2014

How do I get all of my actions and 3rd party filters from Photoshop CC to Photoshop CC 2014?

If you migrate your CC presets you should get your Actions, Pattens, Sahapes, Shapes etc back. Menu Edit>Presets>Migrare Presets. You need to copy or to install you 3rd Party plug-ins into CC 2014.

Measure pulsewidths and amplitudes of 3-phase pulse using PXI-5122

Hello,
I am trying to measure the pulsewidth and amplitude of each of the three sections of the attached pulse. Basically there will be two negative sections and a positive section in between. Each may have a different amplitude and/or pulsewidth. Is there any fairly easy way to do this on the 5122 (using CVI)? I was thinking perhaps there's a way to only capture each of the three segments separately, and let the digitizer do the relatively simple analysis. Please see the attachment for a picture of what I'm trying to measure.
Thanks!
P.S. If you can figure out a method for measuring the deadtime in between the 3 sections, and a method for determining whether the pulse is fairly square, you get extra points.

determining whether the pulse is fairly square ....
Using a Histogram of all pulse values? If it is a pure pulse all values will be in two bins ....
You didn't provide a coarse time scale. Is it p/n/µ/m seconds?
So my approach out of the cristal ball:
Set up the 5122 to absolute timescale , set up trigger to 5% pretrigger with multiple shots , each shot long enough to hold one tripple pulse
fetch one shot , seperate the pulses (find slopes seperate inbetween) , make histogram.... do analysis (hope you have the time for it)
time between tripple pulse is the difference in the trigger timestamp
(In LabVIEW I would use multiple loops in parrallel with queues... )

Unable to Install Windows Server 2012 R2; system aborts and reboots after first blue Windows logo appears

System: Dell PowerEdge sc1420 with dual xeon and Adaptec 2420SA SATA RAID (supported by OS); 10 GB memory (2x4, rank 2, organization x4, in DIMM1 & DIMM2; 2x1, registered, organization x8, in DIMM3 & DIMM4)
This computer is currently running Windows Server 2008 R2 Enterprise which was installed with no problems.
Objective: clean install of Windows Server 2012 R2 Standard on an otherwise unused RAID array disk set.
All attempts to boot from DVD result in loading of files (grey progress bar on bottom of screen), brief dark screen, then black screen with a blue windows logo for about 2 seconds and then a flash of about 10 lines of error notifications on a black screen
for about 1/4 second (unreadable), and then a reboot of the computer.
Coreinfo.exe confirms that cpus DO support NX and PAE; do NOT support VMX (virtual machine enhancements).
Attempts to run memtest.exe from boot disk tool-menu startup result in an error message that the memtest.exe file is corrupt.
Running memtest.exe from Windows 2008 R2 install disk results in all memory tests passed!
Attempted booting with multiple DVD's (some +R, some -R, all verified) burned from .iso. These DVD's were used successfully to install Windows Server 2012 R2 on an HP Pavilion. Also changed DVD drives just to rule out DVD hardware.
Running CHKDSK from Windows 2012 R2 on HP Pavilion shows no problems; running CHKDSK from Windows 2008 R2 on the Dell system on the same disks shows some problems. Running checkdisk on the Windows 2008 R2 install disk from the Windows 2008 R2 installed
system shows no problems. All disks burned and verified on same system.
Also attempted to boot from USB thumbdrive with copy of DVD on it. Same results: system loads files then reboots at first Windows logo. So that would rule out disk quality issues per se??
Started to try an upgrade rather clean install to see if any errors were announced. None were announced as the system went through much of the process. I aborted somewhere along the way before committing to the upgrade because 1) the most likely
outcome was it would not boot after install (I don't really need the practice in restoring); and 2) even if it did reboot, having a system that can't be repaired by booting the install disk is pointless.
All disks and raid arrays are recognized and usable by RAID controller card and by Windows Server 2008 R2. Disks are within spec for use with Adaptec 2420SA (1TB @ 300).
Is VMX (aka VT-x) actaully required for ANY install even though Hyper-V is not intended to be used? If so, it is too bad that the Microsoft system requirements (
http://technet.microsoft.com/en-us/library/dn303418.aspx ) don't make that clear. And lack of VMX support really doesn't explain the memtest.exe "corruption" issue.
Or is it maybe something unique about the files on 2012 R2 disk (or disk image on USB) that are causing some problem with the chipset processing? But why?
My vote would be for the latter of the issues, but I have no clue why or if it is remediable. Suggestions?

So here is what I think is the final understanding of this problem:
First, one additional piece of important information: The computer successfully moves into and through the Windows Boot Loader phase and succeeding phase ONLY for Windows 8.1 32-bit, but NOT for Windows 8.1 64-bit nor for Windows
Server 2012 R2 (only 64-bit).
The Windows Boot Manager phase (which precedes the Windows Boot Loader phase) is either 32-bit or 64-bit (64 –bit for this case) and is loaded by the 16-bit stub program (Bootmgr) which starts in real mode.
Windows Boot Loader of course runs in either 32-bit or 64-bit (64 –bit for this case) according to the product being installed.
By inference, the essential problem is occurring in conjunction with the loading of a WIM file to start the Windows Boot Manager.
The boot manager starts ok and generally shows its essential screens (Windows Boot Manager; Advanced Boot Options) or proceeds to load files for transition into Windows startup in the succeeding Windows Boot Loader phase (that doesn’t “boot” but rather
loads the system). This is best confirmed by the announced corruption of the memtest.exe file when selecting Windows Memory Diagnostic from the Windows Boot Manager Screen.
If allowed to continue loading files to pass control to the Windows Boot Manager, the type of abort and resulting immediate restart that occurs is that which you would associate with unhandled cpu exceptions (invalid instruction, memory out of range,
wild interrupt, etc.) that most of us have not commonly seen for 20 years (since beginning to use well behave OS’s from Windows NT 3.1 and on).
So, the problem obviously is due to a failure to properly mount the WIM file and/or properly access it (probably the latter) when running in 64-bit protected mode.
This is independent of the hardware on which the install disk is actually mounted (DVD or USB-flash), so it is NOT a hardware problem
per se.
Since the WIM is mounted early in the process, Boot Manager may well have loaded it using BIOS routines to access the physical device on which it resides rather than loading 32-bit or 64-bit drivers of its own.
Hence, if the BIOS does not “mount” the WIM in a way that is later fully compatible with access from the 64-bit systems being loaded, it could cause apparent file corruption.
If it is only partially incompatible some functionality may appear quite usable (like loading files) until later detected.
This is vague on my part, because the exact nature of the incompatibility cannot be readily determined from the information available.
But the consequence is the same: the system cannot boot from the install disk, either for initial installation or repairs.
Incidental conclusion: The 64-bit boot manager code for Windows Server 2008 does not exhibit this faulty behavior, but the 64-bit code for Windows Server 2012 does.
So the problem is not inherent with loading 64-bit server OS’s.
Expectations: If the system were to be upgraded using the features of the install disk while running an installed OS, say Windows Server 2008 R2, it might well succeed and yield a fully functional system upgraded to Windows Server 2012
R2 (because the installed operating system is started from discrete files, not from a WIM file).
However, in order to perform a disaster recovery using Windows resources (such as image backups from Windows Server Backup), one would have to presumably boot from a Windows Server 2012 64-bit install disk or Windows Server USB recovery drive.
Of course we know that the Windows Server install disk will not boot and we can be fairly sure that the problem will migrate to any Windows Server USB recovery drive that is created.
My inspection of a Windows 7 System Repair CD shows that is based exclusively on boot.wim, not discrete files!
Of course a generated image for a WIM for Windows 2012 USB recovery drive
might not have the flaw that drives this behavior, but it probably would.
Problem conclusion: A BIOS upgrade would be required for compatibility with Windows Server 2014 clean installation
and any maintenance; and none is available from the OEM.
Problem not resolved, but understood for future reference.
Thanks to Tim whose comments helped me focus my thinking.
