Direct digital frequency synthesizer
Svoboda, Josef ; Šebesta, Jiří (referee) ; Kasal, Miroslav (advisor)
Direct Digital Frequency Synthesis (DDFS) is a method of producing an analog waveform, usually a sine wave, by generating a time varying signal in digital form a then performing a digital to analog conversion. Because operations within a DDFS device are primarily digital, it can offer fast switching between output frequencies, fine frequency resolution and operation over a broad spectrum of frequencies.
