Hello everyone, I want to calculate true rms from samples and wonder if the window size must be an integer of the period of the signal. (I'm very lazy to measure the frequency of signal )
If there is an error with using non integer window size, how can be calculated?
Ah, the formula I saw in internet is
w
Vrms= sqrt(sum(V[n]*V[n])/Window)
n=1
Thanks in advance
