To increase the amplitude of a spectrum
hello,
I have a spectrum and I would like to increase the amplitudes of the fundamental frequency and harmoniques. Is it possible ???
Thank you ?
Hi,
When using "Harmonic distortion analyzer.vi" you can get the fundamental frequency and its multiples in array.
Take the array and perform the scaling you need.
But if you need to increase harmonics for the original signal, this is completely different story which I have no idea how to do it.
The attached VI shows performing an addition to the harmonics detected from a signal.

How does one increase the y-axis (amplitude) of the audio tracks?
How does one increase the y-axis (amplitude) of the audio tracks? My patient appears to have flatlined. I don't want to increase the gain, just the way the waveform looks on my monitor.

The "Expert view" is a part of the new interface of Premiere Elements 11. In your version 10, you have the Timeline and the Sceneline view choices.
For now, I will assume that you are in the Timeline view where you utilize video and audio tracks and not a Filmstrip with scene slots.
I suspect that you may be after the following. Let us see.
To the right of where it shows the name "Audio 1" is a microphone icon. That represents the "Audio Display Style". There are two Audio Display Styles and you can select one or the other by toggling that microphone icon.
a. In one instance, you will see the wave form plus a horizontal orange line which is typically the Volume Rubberband for Volume adjust. This Display Style has a light green background.
and
b. In the other case, you will see a dark horizontal line, no wave form. That dark line is on a light green background.
I suspect you are at "b". Are you aware that "a" exists.
If you want a really blown up version of "a" to look at, you could separate the audio from the video, double click the audio to open the Preview Windows, and then scale up the Preview Window.
We will be watching for your follow up to see if we are getting in sync.
Thanks.

Most efficient way to extract the amplitude of a signal and display on an intensity graph
Hi All,
I am having difficulty to display the amplitude of an voltage signal (voltage picked up by NI DAQ card).
what I am trying: Voltage signal (Dynamic data type)--> 2D array of dynamic data type (using 2 nested for loops) --> normal 2D array with scalar values --> intensity graph
I have difficulty to convert the dynamic 2D array to scalar 2D arry.
I only want to extract the amplitude of the imcoming signal.. any body can give some advice? thanks in advance..
CharlieHi Hillary,
Thanks for your reply.
Yes, I did tried to use Amplitude and Levels Express vi, it should be the one I am looking for, but I found it not work in my case, I need to put the value of amplitudes into a 2D array.
If I use Amplitude and Levels Express vi, it will give me a 3D array, I have found the solution, just convert the dynamic data to single scalar. (see pic attached)
Anybody can help me to solve the following 2 problems:
1. The speed of this program is too low, i think ii due to the DAQ assistant in the 2 for loops (for creating 2D array), it should be able to re-write using DAQmx (as "centerbolt" told me), I am working on this now, if anybody can help, I will appreciate that.
2. Is there any other way to creat the 2D array (for purpose of increasing speed also).
Thanks,

How to increase the speed of producer-consumer architecture
Hey everyone -
This is a follow-up to a previous thread that I had posted (
http://forums.ni.com/t5/LabVIEW/How-to-use-a-dynamic-true-false-signal-with-a-case-structure/m-p/114...
), but my next question has taken a bit of a different direction so I have made a new thread.
Following tbob's suggestion, I am trying to use a producer-consumer architecture to start and stop data acquisition from a simulated NI 9237 device. I have attached the current version of our code to this post (Producer_Consumer_architecture.vi). Our main problem is that there is a significant lag between when elements get added to the queue using the Enqueue function, and when they are removed from the queue using the Dequeue function. As a result, the signals from our simulated DAQ channels run for much longer than they are supposed to, and the start-and-stop of data acquisition is not keeping in time with the simulated square wave signal (we would like our NI 9237 device to acquire data when the square wave has an amplitude over 3, and stop acquiring when the amplitude is under 3). If you allow the program to run for about 30 seconds, you will see what I mean (press the stop button twice to quit the program).
If anybody has any suggestions as to how we can increase the speed of the program, they would be very much appreciated!
Thanks in advance!

Save_data.vi 14 KBhello,
i don't have tools needed but , i see one thing is that you enqueue
every time you are greater 3 that means about every 2-3 ms so consumer is really sought
is it really what you want ?
may be you want to start on a treshold so you can use a treshold fonction
if i don't make mistake your square is 10 hz and the daq is configured 25000 sample 25000 hz
so you aquire 1s of signal every 100ms , there is something to correct
make tests and tell us

What is the difference between power spectrum and PSD?
Hi all,
I input a time domain signal to the FFT power spectrum VI and FFT PSD VI seperately, and got two outputs in frequency domain with similar shapes but different magnitudes.
I refer to some signal and system textbook, and find PSD(w)=1/pi*Power Specrum or equivalently PSD(f)=2* Power Specrum.But as I observed from the LabVIEW outputs, this relation is not correct. I input a 1KHz sin wave with amplitude=1, Fs=512KHz, #s=2048 , the PS peak is 0.5 and the PSD peak is around 0.013.
So I wondered what's the real formula LabVIEW is using to calculate PSD?
SunnyPSD is related to spectrum resolution, thus related to sample rate.
df= Sample rate/ #samples
I think they follow this relationship:
Amplitude FFT power spectrum = Amplitude PSD * df * 1.5 -
Ctx_doc.snippet increase the number of occurrences returned
Hi everybody,
I am pretty new on Oracle Text so please be merciful :)
I am on Oracle 10.2.0.4.0 and I need to provide my users with ALL snippets found in a text, but it seems that CTX_DOC.SNIPPET restricts the number of snippets occurrences (I will exemplify it later).
The question is: is there a way to increase the number of results/snippets returned by CTX_DOC.SNIPPET ?
In the example that follows, I create the table "mysearch" and an index of type CTXSYS.CONTEXT, then I run the final SELECT query with CTX_DOC.SNIPPET() to obtain a list of most relevant fragments.
If you run the query - see the column "SNIPPET" - record #6 is returning only the first 4 occurrences. In this case (especially because is a single row) I would expect to find all 6 occurrences instead of 4.
Again, if looking to record #7 I have only 3 occurrences.
Then for record #8 I have only 2 occurrences.
I know that CTX_DOC.SNIPPET retrieves the "most" relevant fragment, but I would like to obtain the full list of fragments present in the indexed text. Is there a way (or an alternate method) to accomplish what I like to do.
I have also noted that CTX_DOC.MARKUP can be used on the same index to retrieve the full text "marked-up" with my query terms, so I know Oracle has indexed the text somewhere, I need only to get it out !
Any help will be very appreciated.
Thanks,
Luigi

Whats the best option to increase the speed on my mid 2010 macbook pro?
What choices are there for me to increase the speed of my computer ?
More RAM and a SSD. If you're running under 8GB of RAM, I would recommend upgrading to 8GB. You can check out Crucial or OWC for the correct RAM configuration for your model.
While you're at Crucial, I would also look at the available SSDs that would fit your machine - just use the System Scanner tab, and it will show you the recommended upgrades.
RAM and SSDs are about the only things you can upgrade to make your computer faster.
If you're new to SSDs, see my user tip here -> https://discussions.apple.com/docs/DOC-4741.
Good luck,

The data transfer phase is still running (99% - 60hs running). We analyzed the Display Runtime Information report and see that objects of conversion with similar calc. records and calc. GBytes have very different the Net Runtime.
TMDS currently is working with four objects of conversion, processing a portion of each.
Conversion objects that are running are:
- Z_LTBP_002
- Z_TSEGE_002
- Z_VEVW_002
- Z_YST27_002
We check in the receiver system, and we see that is use only one DIA process to update the each table.
How can increase the performance of the update? Is correct that use only 1 DIA process for this??
Can I increase the number of portions in process for each conversion object?
Any help is greatly appreciated.
Regards,
SergioHi,

How to Increase the 15 Minute Idle Timeout?
I saw some similar posts to increasing the EM timeout, but they didn't seem to relate to the idle timeout period.
I need to increase the idle timeout from 15 minutes to something more like 30 minutes. A lot of times, I'll be editing a package with 10g on the web and doing some research online in between edits, only to come back and be timed out for no activity within 15 minutes. That's just too short. Can I increase the time? Where can I find that setting?
Thanks!Change or Add the parameter in emoms.properties
For DBconsole
$ORACLE_HOME/servername.domain_SID/sysman/config/emoms.properties
For Grid Control
$ORACLE_HOME/sysman/config/emoms.properties
For example, you can change this time to 60 minutes (1 hours) by adding the following lines to the above file.
oracle.sysman.eml.maxInactiveTime=60 -

I am doing an an aquisition and displaying the data on graphs. When I run the program it is slow. I think because I have the number of scans to read associated with my scan rate. It takes the number of seconds I want to display on the chart times the scan rate and feeds that into the number of samples to read at a time from the AI read. The problem is that it stalls until the data points are aquired and displayed so I cannot click or change values on the front panel until the updates occur on the graph. What can I do to be able to help this?

It may also be your graphics card. LabVIEW can max the CPU and you
