Find out the peaks and check them against a value
Hi
I am currently aquiring a bunch of signals (4 to be exact) through a 6120 card. This works as expected.
Now I'd like to check all 4 signals if any value (up to 80 000 samples / waveform) has it's lowest level above -0,8 V and it's highest level below 0,8 V.
I tried this with the Express VI (Level and Amplitude Measurements). I check both for the peaks and if one of them (OR) is above/below that value, a Boolean value should change.
So I have my 1D - Waveform Array as Input to the Express VI. I then get the Positive/Negative Peak. I wire those to smaller/grater sign. and when I try to wire the two outputs of the smaller/greater signs to an "OR", LabView won't let me
It says: Source is Dynamic Data, Sink is Boolean.
What am I doing wrong ?
It would have worked, if you had converted the dynamic-data to a double before you pass it to the > / < operators.
If you pass two different data types to a function, the "lower" is converted to the higher (e.g.: sgl -> dbl) which is why the dynamic data is passed on to the or-operator.
Just see this example.

Can I find out the peak of Output 1-2 without having to play whole track?
Can I find out the peak of Output 1-2 without having to play whole track? I am preparing my album for mastering and I was told to have each track peak at no more than -2dB. Is there an offline peak detector or maybe another trick people use?
You should deliver your mixes to the mastering house in 24bit format. They should be converted to 16bit and dithered AFTER the mastering. Also, as long as the mixes are not overloaded, the levels could be handled in mastering also. That's what mastering is about, matching the perceived levels between the tracks. As far as your last question, "Do you just slap a multipressor on the output at that point and call it mastered?" the answer is heck no. I'd suggest selecting some professionally mastered cds in your genre, and put a few into your "mastering song" in logic and use them to compare to your mixes. Play with the mastering tools (multi compressor, EQ, adlimiter, etc) on your tracks and try to bring them into the ballpark with the reference songs. It will take a while to get a handle on it, but with practice, it will get you there.

How can i find out the resolution and accuracy of PXI-6602 module?
I have a 32 bit 8 channel PXI-6602 counter module. PXI card is interfaced to PC with MXI-4 link. How can i find out the resolution and accuracy of this system.What is the maximum accuracy and resolution i will get from this system. Because optical signal to cmos conversion signal is given as a input to the counter.
Hi chandhu,
Were you referring to the accuracy of the count register or the timing clock?
PXI-6602 specifications can be found in the NI 660x Specifications. The resolution of the count register is, as you’ve noted, 32 bits. This corresponds to a maximum count value of 4,294,967,295. As long as all of the edges are in accordance with TTL specifications, the accuracy of the count register is 100%.
On the other hand, the PXI-6602 baseclock accuracy takes on the baseclock accuracy of the PXI CLK 10 signal. Again, this is all found in the specifications.
You may also want to check out the NI 660x User Manual – it contains a lot of details on the operation of these counter/timer devices.
I hope this helps. Please post back if you have further questions.

Find out the peak position from graph
Hello All,,
Actually i want to run this algorithm real time,, to find out the peak position from graph ,, i need to generate the position automatically,,, firstly i try to use image processing by apply threshold followed by edge detection and the find out the center of each detected part. the drawpack of this procedure is that the obtained images are different and that lead to different threshold values,, so how can i directly find the position from the graph,,, here i attach the image and the graph of the image,,
thank you,,

13.PNG 85 KBHello Klemen:
here i will explain in more details: the main objective of my work is to calculate velocity of small particle,, i perform my experiments by exposing the particle to 2 light pulses,, and i know the time between the two pulses,, so i need to know the distance to calculate the velocity,,, for that i apply correlation,,, the spot that appear in the correlation image is an indication of symmetry,,,so i should know the location of maximum intensity of each peak. The central peak (highest intensity) will be the reference (zero point) and the other peaks locations should be subtracted from the reference peak to determine the shift,,,
Here is the sequence of the process:
Acquiring raw image, correlation, position of central peak, shift calculation, velocity determination,,,,,
applying image processing is good idea in case of post processing condition,,, but in my case i need it real time, that mean if i need to apply image processing for calculation, i have to find out a universal criteria for threshold value that can be applied for all raw images,, from my experiments i didn't find specific criteria & i have to manually change the threshold value,,
If I choose the intensity (grey level) to be the criteria, then the small peaks (symmetry) will not take place,, because their intensity is very low compare to the central peak,,,
So the most reliable procedure is to directly find out the position of the two small peaks beside the central peak and save this values into an array and use it for calculation,,, I hope I am clearly explain my problem..
Thanks
