| Abstract: | The general principle of direct digital frequency synthesizer(DDFS) is introduced and its improving version is proposed in the paper. A sin/cos signal generator using this version has been designed,having both the frequency range from 0.01Hz to 30kHz with frequency in interval 0.01Hz and the standard frequency stability of crystal oscillator. |
