Pulse-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… … Wikipedia
Pulse-width modulation — (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… … Wikipedia
pulse-code modulation — /puls kohd /, Telecommunications. a form of modulation that transforms a wave form, as an audio signal, into a binary signal in which information is conveyed by a coded order of pulses for transmission, storage on a disk, or processing by a… … Useful english dictionary
pulse time modulation — noun : modulation of the time intervals between successive pulses of constant duration and amplitude in accordance with a signal; specifically : a system of multiplex high frequency transmission using this method of modulation … Useful english dictionary

Pulse Frequency Modulation — (PFM) is a modulation method for representing an analog signal using only digital levels (1 and 0). It is analogous to pulse width modulation (PWM), to which the reader may refer for more detailed information, as the magnitude of an analog signal … Wikipedia
Pulse generator — Pulse generators can either be internal circuits or pieces of electronic test equipment used to generate pulses. Features Simple pulse generators usually allow control of the pulse repetition rate (frequency), pulse width, delay with respect to… … 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
Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
