Abstract
A frequency dither technique is used for reducing spurs due to phase increment errors in a direct digital synthesizer output sinusoid. The spurs for a desired output frequency are calculated and, if the spurs fall within a phase locked loop bandwidth, a pair of phase increment values are used representing a pair of frequencies that average to the desired output frequency and the spurs of which fall outside the phase locked loop bandwidth.
