Abstract
The digital frequency meter can not only accurately complete the measurement of
the pulse wave, triangle wave, sine wave and other signals, but also can complete their
precise measurement of the corresponding pulse frequency and its frequency cycle, using
the digital frequency meter can make pulse width frequency meter.
The system is mainly composed of four major combinations of signal source
management module, control circuit module, counter control module, latch control
module an
