Abstract
A numerically controlled oscillator (NCO) system for generating rational frequencies with normalized phase is disclosed. In one embodiment, the system comprises a rational NCO and a simple NCO. The rational NCO generates an overflow or correction value, based on a desired rational frequency of the system, and the simple NCO uses the overflow or correction value to generate the desired rational frequency.
