以CPLD器件EPM7128SLC84-15为核心实现的简易数字频率计,采用在一定时间内对数字脉冲计数的方法,可直接测量TTL电平的数字脉冲信号的频率、周期和脉宽。其他一些信号可经过信号预处理电路变换后测量。
量程:1Hz~999999Hz
输入信号:(1)TTL电平数字脉冲信号;(2)方波/正弦波,幅度0.5~5V
显示:七段数码管显示频率(Hz)和周期/脉宽(us)
控制:两个拨码开关切换三种工作模式:测频率,测周期,测脉宽-Frequency Counter realized with Altera EPM7128SLC84-15. It can measure frequecy, cycle and pulse width of TTL sigals.
