Signal manipulati​on---help?

hey,
i am trying to simulate a vibration (accl vs time) signal by reading from a spreadsheet with about 15000 data points(time and accl).
i am reading the two colomns from the sprdsheet and plotting them on a XY graph in a auto indexed for loop(so that they are plotted one by one).
i have also created a waveform using the values and am able to get the spectral output.
however thats all i'm able to do.. i can't do any AMP and LEVEL measurement...i'd like to find the pk-to-pk and RMS value of the signal for all data points... but if i wire AMP&Level to the build waveform i get just one value(of pk-to-pk..max value i think) and if i connect it within the for loop to Y.. i get zero(pk-2-pk).
is there no way i can read from a spreadsheet values and work on them like a actual signal.
i am guessing the reason for this is that all data is read at once and so only one set of values.. isn't there any thing i can do..
thanx,
DiPS

Hello,
2 things... If You just wanna do the measurement one time you can do like I show you in the example.
I you wanna do that measurement as the graph it's growing in the graph, you should have an empty array connected to a shfit register that grows  as your graph and the amplitude measurement inside the loop.

  • Hdmi was working fine , now I am getting no signal, please someone help!!

    I Moved my tv and Macbook pro to another room and now my Hdmi will not work. It keeps saying no signal. Please help!

    gfxCardStatus is a 3rd party product that you would have had to install.  The fact that you are asking what gfxCardStatus is, most likely you have not installed it.
    gfxCardStatus will have an entry in your menu bar.  The letter displayed will reflect which graphic mode it is using.  'i' will be used if in Integrated Only.
    If you did not install gfxCardStatus or similar utility, then chances are that is not an issue for you.

    "no service" happens once everyday, and when i restart my phone, signal goes back. So everyday, i turn my phone on and off to get my signal back..HELP!

    i had this problem on 5.0.1 Firmware, sometimes it would fix using the Airplane Mode Switch (turning it off and turning it back on)..
    are you on Firmware 5.1.1?

  • My Ellipsis 8 can no longer detect my gym's wifi signal. Please help!

    I used my Ellipsis 8 to watch Netflix over the open wifi signal at my gym for 2 months with no problem. One day I showed up and no signal was found. I went through all the trouble shooting steps all the way down to factory resets with no resolution. Called Verizon tech support and still nothing. They had me send them the tablet in a recovery box. One week later I have the tablet back and they said nothing was wrong with the unit. I went to the gym today and it still can not detect the signal. My Samsung phone picks up a very strong signal. No other people have reported a problem with wifi connection issues. Obviously Planet Fitness will not allow me to start messing with their router. Any suggestions would be GREATLY APPRECIATED!

    I understand the importance of ensuring you are able to get connected to wifi michaeltatham. Allow us to get to the bottom of your tablet concerns. Have you recently installed any new software or new applications when it stopped connecting to the gym wifi? Have you tried to connect another device to your gym wifi?
    Thank You,

  • Imac G5 Airport very weak, no signal, problem anyone help?

    Hello all, I just got my Imac G5, Rev A, back from getting the powersupply replaced (it was a recall some time ago; mine started to power down only lately on its own). However, when I got the Imac back it only just bareley registers my Airport Express...I've tried rebooting, reinstalling, etc. My Ibook laptop picks up the signal at full strength anywhere in my apartment, so i know something is wrong with the mac and not the signal. I've tried to take out the airport card and see if its plugged in snug, etc. I'm beginning to think that when the techs were changing the power supply they might have shorted my card or perhaps the antenna system??? Anyone help? I"m out of warranty, but I figure if i call them and tell them the situation they might fix it regardless...i'd love some advice guys, thanks.

  • Flying Blind with an HP Pavilion Elite m9452p - no video signal at all -- HELP!!

    This is a Core2 Quad Intel Q8200 Processor PC with 8GB of RAM and 750 GB HDD + 1 TB back up drive running Windows 7 Ultimate 64bit (it came with Vista 64 bit Home Premium, but upgraded to win 7 a while back).
    It has always performed flawlessly, but last week there was no video at all when I turned it on. The monitor said "No Signal" on an otherwise black screen when powered up.
    The HDD lights show activity and I can hear drives spinning, and the LEDs for the DVD and the wireless signal light up as well.  Also, the Ethernet ports LEDs blink and show activity, as does the DVD drive if I put a disc in, but no video at all.
    I have done the following to try to fix this:
    1. I verified that the monitor I was using is working;
    2. I still connected this PC to another working DVI monitor with no luck;
    3. I connected this PC to a working VGA monitor with no luck;
    4. I connected the VGA monitor to the onboard VGA port with no luck;
    5.I tried booting up into BIOS, but again, no video so not sure if it is going to BIOS or not;
    6. I read somewhere that the onboard VGA port will not work if a video card is present so I removed the exisitng video card and connected to the onboard  VGA with no luck;
    7. I purchased a replacement video card (it came with an MSI V240 500 MB PCIex16 card and got an XFX Radeon HD 5450 1GB PCI ex16 card); I  installed the new card and tried it again with no luck;
    8. I don't recall if this PC was set to beep on POST before as it always started quickly and with no problems. Now that I am looking for any beeps, I don't hear any but again, don't recall if it ever did beep before;
    9. Seems like this is a hardware issue, but I also tried booting to a W7 64 Bit repair disc, but again, no video so don't know if it is working.
    The last thing I recall seeing on it was a Windows Update that I think included an optional update for the video driver. I don't recall if I acdcpeted that one or not, but it seems to me that the drivers for the MSI card (nVidia, GE Force drivers I believe) would be irrelevant with a Radeon card using AMD drivers - that's why I opted to get the Radeon card).
    I have not tested the original card, mainly because I don't have any PC with which to test it (I have a Core 2 Duo Pc with a PCI ex slot but not a PCI ex16. I don't know if this card would be backward compatible to that PC or not).
    I vaguely recall disabling the onboard VGA in BIOS, but don't recall if that was with this PC or another one.
    I am hoping that someone has a way to get the video back on so i can uninstall any recent drivers or updates that may have caused this (or so I can enable onboard VGA in BIOS).
    I sure hope the MoBo is not messed up (it does power up the HDDs, the DVD drive and the fans, etc.) but with no video it's hard to know what's going on.
    Help!!
    This question was solved.
    View Solution.

    OK - SOLVED!!
    After re-reading my post, I realized if the BIOS setting for onboard video had in fact been changed,  I could re-set these to factory default settings by resetting the CMOS.
    I had not tried to clear CMOS via the MoBo jumpers, so I got the MoBo manual and I cleared the CMOs (which would reset the BIOS to factory settings). I re-started the PC and voila! I now have video!!
    Sometimes the simplest things will solve the whole problem!
    I felt bad that I could not resolve this problem as i usually can fix anything that is out on any of my systems, but lo and behold I answered my oiwn questin and solved the issue -- hopefully this will help others too!

  • TV NO SIGNAL!-PLEASE HELP!!

    Hello all,
    I'm currently house sitting for a friend whilst she's away and all of a sudden all (3) of the TV's just say 'no signal' when I switch them on-It started yesterday with the one in the lounge (whilst the one in my bedroom worked fine last night)-But today nothings working...I tried the standard 'un-plugging' everything for a few mins but to no avail
    I really want to get it sorted before she comes back from mholiday this Sat but cant afford to call out a technician...please help!
    Many thanks :-))

    Have you turned anything off? If the aerial feed goes via a Vision box or similar it will need to be powered to pass the signal through (on or standby mode are fine but it won't work if you turn the power off).

  • Solaris HotSpot Virtual Machine Error, Unexpected Signal 11 NEED HELP

    Hi all
    We are running a thin jsp application for video streaming live event running
    on a BEA WebLogic Personalization Server 3.2 on Solaris (streaming servers
    are separate and do not affect the server). After putting it in production
    we have experienced serious memory problems with our environment. When the
    servers are running under heavy load, they eat all available memory until
    they finally crash, please see log message below. We can see that the
    garbage collection is running but it doesn't seem to keep up with the memory
    consumption. The problem is described in a bug report at SUN, but it is
    marked as a "no fix" with the reasoning that programming resources are now
    allocated to jdk1.4?
    Log message:

    We have now upgraded to jdk1.3.1_02 B02 but still have a problem with memory
    leaks. We have so far been able to restart the server before memory is
    exhausted and has hence not seen the same error message after the upgrade.
    The memory is not freed when Weblogic aborts, the SUN server has to be
    rebooted to free the memory. We now have to restart our 3 servers aprox.
    every 6 hours. The servers are equiped with 2G physical memory each. We have
    also tried setting hotspot to -client and setting -XX:MaxPerm.
    The HW configuration is as follows:
    1 Foundry Server Iron load balancer (with one hot stand by).
    3 Sun E420R, 2 x 440MHz CPU, 2GB RAM. Running in a cluster with one apache
    and one WLPS instance on each

    This bug is described in
    http://developer.java.sun.com/developer/bugParade/bugs/4408730.html.
    It is also described as a known problem in
    http://www.weblogic.com/platforms/sun/index.html.
    It has also been described by SUN as a problem arising from multiple nested
    try/catch blocks appearing in generated java code from servlets, especially
    on WebLogic and Apache.
    As SUN has said that they will not fix this bug we are trying to find a
    workaround, but have yet found one. We have been looking into changing the
    heap size and setting GC options on the JVM, but haven't found the optimal
    solution. We would be very interested in experiences with tuning gc
    parameters, documentation on solaris patches for JVMs, JVM tuning, WebLogic
    tuning, HotSpot tuning.
    Has anyone experienced similar problems and found a workaround. We would be
    very happy to hear any suggestions as soon as possible,
    thanks

    Perhaps the -noTryBlocks option to jspc might help you. See here:

  • Airport does not recognize any networks, no signal whatsoever, SOMEONE HELP

    Hello, I use an iBook at the office, i have been using it for several months here and at home, worked fine until yesterday, logged on in the morning everything was working fine, until airport had no signal, it did not recognize any networks, at first i thought it was a problem here at the office, all the other computers are working.
    I tried it at home and it doesn´t recognize anything at all.
    The network status says that airport is turned on but it is not connected to any network.
    It`s clearly a problem with my computer, not the network, can anyone help?
    Regards
    Rodrigo

    Rod1, Welcome to the discussion area!
    Verify that the antenna wire is still properly connected to the AirPort card. It may have come loose.
    If you have an iBook G4 you can use the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card to verify that the antenna wire is still properly connected to the AirPort Extreme card.

  • Ipad2 connected to lcd projector showing no signal...Help..

    Today, I tried to use my ipad2 for presentation ( by using Keynote app) in college. I plugged in my apple VGA adapter and the projector cable connected with my ipad2. Nothing happened. The projector screen kept on saying there was no output, no display at all and no signal. What should I do????????? Anyone..pls help...

    Thank you for your quick response to my question.  The Apple Genius Bar tried adjusting the color settings in my MacBookPro, as stated in the document you attached.  It did not help ... my Keynote lectures are still pastel, and my x-rays are blue & white. I should have stated this in my original query for help.
    Again, many thanks for responding.
    Did the Apple Genius explain to you why it did not work or even if it's possible?

  • Poor wireless signal quality, please help?

    I am projected at getin 60Mbps for my wireless connection, but a week after geetting Infinity, the signal maxes out at 5.5Mbps.
    I am 3 miles from the interchange, but my initial speed test was 58.6Mbps download and 8Mbps upload (I was more than happy with this).
    All hardware related to the internet connection is brand new from BT, we have a new line and ther interchange is in fully-functioning condition.
    What do I do? I can't access the internet at peak times at all >.< I get a stronger signal hosting off my iPhone's 3G connection!

    What speed do you get if you use a direct Ethernet cable from the home hub to the computer?

  • WeBoost cell phone signal boosters could help your reception

    Maybe it’s Murphy’s Law, but dropped calls usually happen at the most inopportune times. An important or engaging conversation cut short by a sudden drop in reception can be annoying—even more so if it happens with any sort of regularity. Cell phone signal boosters are designed to amplify sending and receiving those signals, and weBoost has products that cover both your car and home.
