I have a CDAQ9178, with a 9229 4ch sigma delta analgoue card.
I have two sine waves around 5V pk to pk at a frequency of 10hz. each waveform varies in cycle width and cycle ampltiude.
I am recording 2 seconds of data, sampling at 10Khz. i want to be able to measure the following for each waveform and ouput the data into an array
- Cycle Postive width (for each waveform)
- Cycle Negative width (for each waveform)
- Postive Amplitude (for each waveform)
- Negative Amplitude (for each waveform)
Does any one have any information on how i can do this. Using the DAQMX vi all i get is an average. For the application i need it for 'average' will not work.
what DAQmx vi are you talking about? If you have a waveform you can use some of vis from Signal Processing >> Waveform Measurement palette for analysis of the signal.
