Let’s say, for the sake of example, that I drop a non-descript box onto your workbench that contains an unidentified gain block. If I say to you ‘measure the PSRR of this device’, how would you go about doing so, i.e. what measurement would you take and how would you derive the dB rejection figure?
I’ve noticed with certain older solid-state items that you can see a ghost of the audio path’s waveform on the DC rail. I assume you could measure this ‘ghost’ and express it as a function of the input amplitude and available dynamic range – correct?
