Direct Digital Synthesizer

What's DDS

DDS is digital frequency generator. DDS is composed of ROM based sinewave look-up table, accumulator, address counter, DA convertor and Low pass filter. It features precision frequency generator with low distorted sinewave. The frequency accuracy depends on the data length of accumulator up to 2^32 bits, for example.
