Hi,
I have an array of a pseudo-sin signal.
I want to get the fundamental magnitude of it knowing the fundamental frequency.
My approach is (about 4-5 command lines)...,
a) fft the signal; b) search for the magnitude of the fundamental frequency; c) show the magnitude.
There is no command to get the fundamental magnitude easily ?
Thanks.
Andre
