Count Based Frequency Meter Electrical Engineering Stack Exchange Can you be more specific on what frequency meter you are referring to? it uses a comparator and possibly a frequency divider to turn the sine wave into the clock signal to a binary counter circuit. a binary counter increments on each clock cycle. see similar questions with these tags. To measure the frequency of a certain periodic signal, the waveform of that signal is used to toggle a counter for a certain xed time. the number of counted cycles per unit time indicates the signal frequency.
Count Based Frequency Meter Electrical Engineering Stack Exchange The problem with counting low frequencies is that as the frequency gets lower you need more and more time to get enough counts and you end up having to wait long periods of time to get updates. The machines at my workshop have meter counters with hall effect sensor switches, which convert shaft rotation to electronic pulses. the switching signal is send to their plcs' high speed counter. I'm trying to build a frequency counter with a resolution of 1 hz that will count any frequency between 0 and 999 hz and hold that value. i've built the following in multisim but i'm having trouble getting it to work. As i change the frequency meter resolution, it changes its gate time, and changes the number of digits it displays. the number of digits it gives is consistent with a 10ns resolution in the timing error correction circuit.

As i change the frequency meter resolution, it changes its gate time, and changes the number of digits it displays. the number of digits it gives is consistent with a 10ns resolution in the timing error correction circuit. I need to count digital pulses with a width of 30 ns and display the updated count to the user every second. the pulses have already been through a comparator and a pulse shaper.
