Hi,
I tried changing the limits to the ones you recommended above, the
result was that the calculated rms value was now higher than the
highest component from the FFT analysis. However the value was over
100V higher, than the value I got from using the waveform points in
the equation for rms, in
In the past we acquired and saved the waveform using an old HP
oscilloscope. The saved waveform was then analzyed using a program
written in HP BASIC on a HP computer. What we are trying to do now is
do away with the HP computer, so that we can analyze the data on a
Windows based PC.
So far we've
I have an application that performs FFT analysis on an AC voltage
singnal. As part of the whole setup, I've also included the Cycle
average and RMS vi. When I've run the whole program, I've found out
that the RMS value indicated is less than the highest magnitude
component from the FFT
