numerically controlled oscillator , DCO (abbreviation)

For transmitters, a numerically controlled oscillator (NCO) also does not have problems with drift.

Uses a numerically controlled oscillator (NCO).

Numerically controlled oscillators offer several advantages over other types of oscillators in terms of agility, accuracy, stability and reliability.

Pure digital oscillators such as a numerically controlled oscillator are used in ADPLLs.

Practical realizations of this principle often employ digital memory to store samples of the single-cycle waveform (see numerically controlled oscillator).

Numerically controlled oscillator (Also "digitally controlled oscillator" or DCO)

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.

It can also be generated digitally by a DSP and DAC, using a Direct digital synthesizer (DDS) and by varying the step in the numerically controlled oscillator.

The term "digitally controlled oscillator" has been used to describe the combination of a voltage-controlled oscillator driven by a control signal from a digital-to-analog converter, and is also sometimes used to describe numerically controlled oscillators.
