摘　　要：电信号的频率是主要参数之一，对它的测量很重要，方法也很多。目前绝大多数采用数字式硬件电路来完成。但由于２８０—ＣＰＵ微处理器运算速度快，控制能力强，据测频原理，可采用软件秒脉冲和软硬件计数器来实现对频率的测量，为ＴＰ８０１单板机增加了测量功能，可一机多用。The frequetlcy of electric signal is one of the essential parameters. Its measurement is very important, and there are many ways to measure it. At Present, the digital circuit with hardware is adopted in most cases. Since 280 - cpu mini - processor can calculate rapidly and its controlling ability is strong,According to the principle of frequency measurement,second-pulse with software and the counter with software and hardware are used to complete the measurement. Thus the functions of frequency measurement to TP801 single plate computer increase,and it can be used for multiple ways.
