To be clear, a peak detector measures the highest peak of any waveform instantaneously and displays it accurately, but an RMS detector measures the square root of the arithmetic mean of samples of the entire wave for, and thus will read differently with different waveforms, though the peak voltage may be the same. peak inverse voltage is the maximum voltage the diode can withstand when it is reverse-biased. Examples: (a) If your narrowest peak has a peak width of 1. peak detector calculator
