• 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 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… …   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

• Sample and hold — In electronics, a sample and hold circuit is used to interface real world signals, by changing analogue signals to a subsequent system such as an analog to digital converter. The purpose of this circuit is to hold the analogue value steady for a… …   Wikipedia

• pulse-chase — An experimental protocol used to determine cellular pathways, such as precursor product relationships. A sample (organism, cell or cellular organelle), is exposed for a relatively brief time to a radioactively labelled molecule, the pulse. It is… …   Dictionary of molecular biology

• Pulse sequence — In Fourier Transform NMR spectroscopy and imaging, a pulse sequence describes a series of radio frequency pulses applied to the sample, such that a free induction decay is induced whose signal can be recorded in the time domain. After applying a… …   Wikipedia
