Principle Of The Electronic Counter

Jun 17, 2016

① frequency measurement: the measured signal from a channel input, if TB is 1 second, reading n is the frequency in kHz of fA. By standard frequency of the oscillator output signal by the time base circuit after appropriate divider gate timing signals and determine the value of TB. ② cycles or time interval measurement: the signal to be measured by the b channel input control gate, a channel input signal is a time base circuit provides clock pulses. Counters count number of gate opening hours, which is the signal cycles or time intervals.
