Re: RMS calculation over one cycle 50/60Hz

Reply posted 1 month ago (10/16/2020)
As Kocsonya has said, with 6kHz sample rate, you get integer multiples for both 50Hz and 60Hz. For 50Hz, you will need to collect 240 samples instead of 200 to...

One way to deal with both 50Hz and 60Hz is to use a frequency multiplier, such as a PLL based one. The output frequency of such a circuit is in sync with but N-times...

It depends on the purpose of the integrator. If it's just for integral calculation, then the forward approximation is more simple,I(k)=I(k-1)+T*x(k)  If it's...
