Re: Confiused abou how to calculate effective power/voltage/current of a pulse wave
So you are saying that the oscilloscope waveform doesn't show the real module current consumption. Then we shouldn't discuss this waveform.
Once again, if a device is supplied with constant voltage, average power consumption isn't but average current multiply voltage.
Pavg = Vconst * Iavg
So the problem is about measuring average supply current.

You are thinking too complicated.I believe the only way to calculate the effective power consumption having such a waveform is to Fourier transform the waveform and choose n to some number of accuracy and find out the rms for the different part of the Fourier series and sum it .. this is the only way to get a correct effective power consumption.
