Dictionary of Computer and Internet Terms: peak-to-peak
peak-to-peak
a way of measuring the voltage of alternating current from the most positive to the most negative point. For example, the audio output of a microphone is about 0.002 volt peak-to-peak; the "line out" from a piece of audio equipment is about 1 volt peak-topeak. Peak-to-peak measurement is used mostly with low-level signals that are viewed on oscilloscopes; ordinary voltmeters usually read rms voltage. The peak-to-peak voltage of a sine wave is 2.828 × the rms voltage. Contrast peak; rms.
