| Abstract: | The Circuit of the simulative circuit signal generator is the same to a bibration circuit made up by operation amplifier and some components. It suffers from such shortcomings debug difficultly, a complicated craft structure and a lower dependability Aimed at these problems, the paper has proposed a kind of ultralow frequency phase displacement crystal signal generator. This system adopts digital wave synthetic technology and it can control the frequency of output signal, wave from and dispersion of phase according to the digital signal. It exhibits the characteristics of high precision for output signal, greater stability and higher regulation accuracy. |
