transmitted pulse
1Pulse compression — is a signal processing technique mainly used in radar, sonar and echography to augment the range resolution as well as the signal to noise ratio. This is achieved by modulating the transmitted pulse and then correlating the received signal with… …
2Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… …
3pulse repetition frequency — In radar, the number of pulses that occur each second. Also called the pulse recurrence rate, or PRR. It should not be confused with the transmission frequency, which is determined by the rate at which cycles are repeated within the transmitted… …
4pulse repetition frequency — 1. In lasers, the number of pulses that occur each second. 2. In radar, the number of pulses that occur each second. Pulse repetition frequency should not be confused with transmission frequency, which is determined by the rate at which cycles… …
5Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of …
6Pulse repetition frequency — (PRF) is the number of pulses transmitted per second by a radar. The reciprocal of this is called the Pulse Repetition Time (PRT), Pulse Repetition Interval (PRI), or Inter Pulse Period (IPP), which is the elapsed time from the beginning of one… …
7pulse dialling — noun A telephone dialling system in which digits are transmitted as electrical pulses, the number of pulses corresponding to the value of each digit • • • Main Entry: ↑pulse …
8Pulse shaping — In digital telecommunication, pulse shaping is the process of changing the waveform of transmitted pulses. Its purpose is to make the transmitted signal suit better to the communication channel by limiting the effective bandwidth of the… …
9Pulse-code modulation — PCM redirects here. For other uses, see PCM (disambiguation). Pulse code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu ray, Compact Disc and …
10Pulse — The rhythmic dilation of an artery resulting from beating of the heart. It is often measured by feeling the arteries of the wrist. * * * Rhythmic dilation of an artery, produced by the increased volume of blood thrown into the vessel by the… …
