该数字频率计除输入级和延时单元外全部采用PMOS集成电路,功能多而线路简单。除能测量频率外,还可测周期,频率比,可做计时器或计数器用,并有自校功能。采样方式可手动或自动。测量结果以五位萤光端面数码管显示。除做为频率计使用外,也可做为模一数变换器的数字读出装置,与不同模一数变换器组合,构成各种数字仪表。
The digital frequency meter in addition to the input stage and delay unit using all PMOS integrated circuits, multi-function and simple line. In addition to measuring the frequency, but also measuring cycle, frequency ratio, can be used as a timer or counter, and has self-school function. Sampling methods can be manual or automatic. Measurement results to five fluorescent end digital display. In addition to being used as a frequency meter, it can also be used as a digital-readout device for analog-to-digital converters, combined with different analog-to-digital converters to form various digital meters.
