PROBE COUPLER

A resonant conductor placed in a waveguide or cavity to insert or extract energy [18].

PROGRAMMED TRACKING

The method that uses known satellite orbital parameters to generate antenna pointing angles [17].

PROPAGATION

Waves traveling through a medium [10].

PULSE

Signal characterized by a steep rise from and decay toward an initial level [9] [12].

PULSE DURATION

PULSE DURATION (PD)—The period of time during which a pulse is present [12].

PULSE MODULATION

A form of modulation in which one of the characteristics of a pulse train is
varied [12].

PULSE OSCILLATOR

A sine-wave oscillator that is turned on and off at specific times. Also known as
a ringing oscillator [9].

PULSE WIDTH

Duration of time between the leading and trailing edges of a pulse [12] [18].

PULSE-AMPLITUDE MODULATION

PULSE-AMPLITUDE MODULATION (PAM)—Pulse modulation in which the amplitude of the pulses is varied by the modulating signal [12].

PULSE-CODE MODULATION

PULSE-CODE MODULATION (PCM)—A modulation system in which the standard values of a quantized wave are indicated by a series of coded pulses [12].
