LED

Light-Emitting Diode.

Octave

A measure of bandwidth.

Peak HOLD

Circuit which for a shorter or longer period of time is
in a position to maintain a peak value display.

Peak Programme Meter (PPM)

An instrument that provides direct measurement of
the peak values of complex electrical signals.

Phase

The difference values which alternating current or
alternating voltage runs through during a period.

Phase Correlation Meter

Instrument that displays the phase relationship
between two input signals, such as left and right
channels of a stereo program.
