In the electronics field, the frequency is a basic parameter, and with many other electrical parameters of the measurement program and the measurement results have a very close relationship. Since the frequency signal anti-interference ability, easy to transport, you can get higher accuracy. Therefore, the frequency of measurement is particularly important, frequency measurement method of getting attention.
Frequency meter as a measuring instrument, often referred to as electronic counter, and its basic function is to measure the signal frequency and cycle frequency meter wide range of applications, it is not only used simple instruments to measure the general, but also widely used in teaching , scientific research, high-precision instrumentation, industrial control and other areas. In digital circuits, digital frequency meter are sequential circuits, it is mainly the trigger memory function by a composition. In the computer and various digital instruments, have been widely used. Prod
