, pulse amplitude
is the magnitude of a pulse
parameter, such as the field intensity, voltage
level, or power
Note 1: Pulse amplitude is measured with respect to a specified reference and therefore should be modified by qualifiers, such as "average", "instantaneous", "peak", or "root-mean-square."
Note 2: Pulse amplitude also applies to the amplitude of frequency- and phase-modulated waveform envelopes.
