Hello fellow physicists!
I have a lab about rectifying and filtering circuits and I was asked to calculated the ripple factor using an oscilloscope.
I managed to get the ripple waveform shown on the oscilloscope, but the thing is there are so many values to read off I have no idea which to use/take.
I know the ripple factor is given by the ratio of V_ac over V_dc
where V_ac is the rms of 1/2 the Vpp of the ripple waveform (am I correct here to get the Vpp and multiply this by 1/2*1/sqrt(3)) i.e. sqrt3 since this is a sawtooth waveform
and V_dc should be given by what? v_rms v_avg.. there are so many values to choose from the oscilloscope I do not know what to do!
