Carotid Pulse: Pulse located on the both side of the neck, under the jawbone. Used for taking a persons heart rate.

Pulse Repetition Rate (PRR): The number of pulses transmitted per second.

Pulse Repetition Frequency (PRF): The number of radar pulses transmitted each second. The pulse transmission rate is automatically lengthened for longer ranges.

Pulse Volume: The volume in which the radar data for one range bin are measured. Defined by the width of the radar beam (app. 1°) and half the length of the transmitted pulse. 1 µs pulses are 150 m deep, . . . View Full Definition

Pulse Radar: A pulse radar transmits a sequence of short pulses of rf energy, and estimates range to the target by measuring the time delay in returned pulses.

Pulse Width Modulation (PWM): Is a way of simulating an analog output by varying high and low signals at intervals proportional to the value.

Pulse Length: The time duration, measured in micro seconds, of a single radar pulse. Also called pulse duration.

Impulse Pay Per View (PPV): The ability to buy a particular program on a last-minute decision. Pushing the 'buy' button on the remote control instead of having to make a phone call.
