| Abstract: | By use of inverter,counter,trigger and some other simple chips, a kind of digital phase transfer circuit was designed. The range of phase angle which can be transfered is from 0° to 360°. In the same time, the digital phase transfer circuit was tested and analyzed with a crystal oscillator circuit after frequency division. The results show that this phase transfer circuit is stable and reliable, the accuracy can reach to 2.8°. |
