Abstract
A digital signal generator includes a numerically controlled oscillator (NCO) configured to generate a modulated phase signal, and to convert the modulated phase signal into a sinusoidal output signal, and a pre-distortion module configured to adjust a phase of the phase-modulated signal prior to conversion to the sinusoidal output signal, and to adjust an amplitude of the sinusoidal output signal to obtain a pre-distorted digital output signal. The phase and amplitude adjustments are frequency dependent, and the pre-distortion module is configured to determine an instantaneous frequency of the NCO by computing a derivative of the modulated phase signal, and to address a memory table correlating the determined instantaneous frequency with the phase and amplitude adjustments.
