Colleagues, I need help/guidance on how to use "FFT Spectrum (Mag-Phase).vi" to perform RMS averaging on sampled strip(s). DAQ produces strip of up to 120.000 samples (max 120sec at max 1kS/s). After that I am asked to do the following:
1) segment the strip into overlaping segments (equally sized) 2) perform RMS averaging on them I am not familiar with this particular technological background and the "customer" also cannot explain how it is being done - he just wants me to perform what his signal analyzer does! I am not even sure the segmentation is compatible with the RMS averaging process. Anyway, lets assume the strip length is 200 samples, the egment size is 40 samples and the overlap is 10 samples. Than obviously I can segment the strip into 6 segments starting at strip positions 0, 29,59,89,119,159. What do I do now? I gues I have to turn the segments into waveforms with dt=1/fs and t0=0? I guess I should put the "FFT Spectrum (Mag-Phase).vi" in a loop with 6 iterations feeding a segment-waveform into the "time signal" connector each iteration? I expect the output is NOT auto-indexed? How to apply it properly actually? Roman Golubovski, MSc Dipl-EEng [EMAIL PROTECTED]
