  • Return-to-zero — (RZ) describes a line code used in telecommunications signals in which the signal drops (returns) to zero between each pulse. This takes place even if a number of consecutive 0 s or 1 s occur in the signal. The signal is self clocking. This means …   Wikipedia

  • Non-return-to-zero — The binary signal is encoded using rectangular pulse amplitude modulation with polar non return to zero code In telecommunication, a non return to zero (NRZ) line code is a binary code in which 1 s are represented by one significant condition… …   Wikipedia

  • Alternate-Phase Return-to-Zero (APRZ) — is an optical signal format. In APRZ the field intensity drops to zero between consecutive bits (RZ), and the field phase alternates between neighbouring bits (AP), so that if the phase of the signal is, for example, 0 in even bits (bit number 2… …   Wikipedia

  • Pulse oximetry — Pulse oximeter Pulse oximetry is a non invasive method allowing the monitoring of the oxygenation of a patient s hemoglobin. A sensor is placed on a thin part of the patient s body, usually a fingertip or earlobe, or in the case of an infant,… …   Wikipedia

  • Pulse-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 …   Wikipedia

  • Pulse-amplitude modulation — Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse amplitude modulation, acronym PAM, is a form of signal modulation where the message information is encoded in the amplitude of a series of signal… …   Wikipedia

  • Pulse-density modulation — Pulse density modulation, or PDM, is a form of modulation used to represent an analog signal in the digital domain. In a PDM signal, specific amplitude values are not encoded into pulses as they would be in PCM. Instead it is the relative density …   Wikipedia

  • Pulse-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 …   Wikipedia
