Dither Injection Applied to Direct Digital Frequency Synthesizer Based on FPGA
Hong Zhang · 2009
In order to restrain the resource consumption in field-programmable gate array(FPGA) and improve the spectrum of direct digital frequency synthesizer(DDFS),dither injection technology is applied to the DDFS design.Simulation results shows that with the given method,the spectrum stray of DDFS based on FPGA can be efficiently suppressed.
