• 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-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-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 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
