摘要
采用AT89C2051单片机设计了一种单片锁相倍频电路,利用片内定时器和数字算法实现了对输入信号的同步锁相和倍频,并输出倍频信号。实验结果验证了设计的正确性。
A single-chip digital phase-locking frequency-multiplier circuit is designed based on the AT89c2051.The circuit can track the input signal in-phase and output the frequencymultiplier signal. It is verified by the experiment results that the design is correct.
