How to extract the effective value of fundamental wave and each harmonic in MATLAB? [Copy link]

I have collected a time domain waveform, but I don't know how to extract the effective values of each harmonic and fundamental wave. I'm urgently looking for relevant code or information.

Search for FFT or DFT in the forum. It should be available there. For example, I searched for https://bbs.eeworld.com.cn/forum ... 66660&highlight=fft You can search for it again.  Details Published on 2019-5-27 20:35
