ABSTRACT

The form factor expresses the relation between the signal’s root mean square value and the average value. The form factor relates to the signal’s waveform in that a small form factor is an indication of a flat waveform, and a large form factor is an indication of a waveform containing peaks. When describing the magnitude of audio signals, comparable methodologies of measurement must be agreed to or there is a risk that differently measured values will not be comparable. The output is an electrical signal that is analogous to the acoustic signal. The peak value describes the instantaneous maximum amplitude value within period of the signal concerned. The peak value can also be the maximum value that is ascertained during any period under consideration, even though the usual designation involves the maximum value within period. Usually, the peak value measurement is used with symmetric signals.
