Absolute phase — refers to the phase of a waveform relative to some standard (strictly speaking, phase is always relative). To the extent that this standard is accepted by all parties, one can speak of an absolute phase in a particular field of application.High… … Wikipedia
Digital phase converter — A digital phase converter creates a three phase power supply from a single phase supply. A digital signal processor (DSP) is used to control power electronic devices to generate a third voltage, which along with the single voltage from the supply … Wikipedia
Amplitude — is the magnitude of change in the oscillating variable, with each oscillation, within an oscillating system. For instance, sound waves are oscillations in atmospheric pressure and their amplitudes are proportional to the change in pressure during … Wikipedia
Numerically controlled oscillator — A numerically controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete time, discrete valued representation of a waveform, usually sinusoidal.[1] NCOs are often used in conjunction with a… … 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
Numerically-controlled oscillator — A numerically controlled oscillator (NCO) or digitally controlled oscillator (DCO) is an electronic system for synthesizing a range of frequencies from a fixed timebase. The name is an analogy with voltage controlled oscillator . Note: the term… … Wikipedia
Carrier recovery — A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal s carrier wave and the receiver s local oscillator for the purpose of coherent demodulation. Example of QPSK… … Wikipedia
