8位十六进制频率计设计 根据频率的定义和频率测量的基本原理，测定信号的频率必须有一个脉宽为1s的输入信号脉冲计数允许信号；1s计数结束后，计数值被锁入锁存器，计数器清零，为下一测频计数周期做好准备。测频控制信号可由一个独立的发生器（FTCTRL）来产生。-8-bit hexadecimal Cymometer designed in accordance with the definition of frequency and frequency of the basic principles of measurement to determine the frequency of the signal must have a pulse width of the input signal for 1s permit pulse counting signal 1s counting after the total value was locked into the lock depositors, counters cleared for the next count cycle frequency measurement ready. Frequency control signal generator may be an independent (FTCTRL) to generate.
