8.1. Numerically Controlled Oscillator (NCO)

There are numerous applications in the world of digital signal processing (DSP) that utilize a numerically controlled oscillator (NCO). An NCO is a programmable oscillator that outputs a digital sinusoid at some user specified frequency and phase. The sinusoid can be fixed at some programmed frequency, or it can be swept or hopped over a band of frequencies. The sinusoid can have a constant phase, or it can be programmed to have multiple or switched phases. It can be a simple or a complex device, depending on the requirements of the application in which the ...
