一种新型数字移相电路的设计
|
摘要
用反相器、计数器和触发器等一些简单的芯片设计了一种新型的数字移相电路,移相范围0°~360°。同时将一种晶体振荡电路分频后对所设计的数字移相电路进行实验分析,结果表明,其精度可达2.8°,且稳定、可靠。
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°.
