A numerically controlled oscillator (NCO) is a digital signal generator, which synthesizes a discrete-time, discrete-valued representation of a sinusoidal waveform. You can typically use NCOs in communication systems. In such systems, they are used as quadrature carrier generators in I-Q mixers, in which baseband data is modulated onto the orthogonal carriers in one of a variety of ways.
