摘要
本设计以新型单片机ＡＴ８９Ｃ５２为核心，充分利用ＡＴ８９Ｃ５２中三个可编程定时／计数器，采用测量Ｎ个信号波形周期的算法，实现了频率、周期的高精度测量。
This paper presents a new method for highly precise ditection of frequency and period of signal. In this method, the Single-Chip Micro-computer AT89C52 is taken as a core part and its three programmable timer/counters are well used and the algorithm for measuring the waveshape period of N signals is also employed.
