The magnitude of a pulse parameter, such as the field intensity, voltage level, current level, or power level.
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.

An increase in pulse duration.
Note: Pulse broadening may be specified by the impulse response, the root-mean-square pulse broadening, or the full-duration-at-half-maximum pulse broadening.

An electromagnetic wave that (a) consists of a series of pulses usually of constant length, amplitude, spacing, and repetition rate when not modulated and (b) usually is used as a subcarrier. [From Weik '89]

Synonym fall time.

A measure (or an expression) of the number of "ones" (marks, pulses) in relation to the total number of digit time slots transmitted. [After T1.408-1990]

See distortion.

1. In a pulse waveform, the interval between (a) the time, during the first transition, that the pulse amplitude reaches a specified fraction (level) of its final amplitude, and (b) the time the pulse amplitude drops, on the last transition, to the same level.
Note: The interval between the 50% points of the final amplitude is usually used to determine… (Read More →)

In a periodic pulse train, the ratio of the pulse duration to the pulse period.

Deprecated synonym for pulse duration.

A device that interfaces concatenated E&M signal paths.
Note 1: A PLR converts a ground, received from the E lead of one signal path, to -48 Vdc, which is applied to the M lead of the concatenated signal path.
Note 2: In many commercial carrier systems, the channel bank cards or modules have a "PLR" option that permits the direct… (Read More →)
