50Hz 60Hz Frequency Generator Circuit Using Crystal Oscillator
50Hz 60Hz Frequency Generator Circuit Using Crystal Oscillator
You can generate 50Hz or 60Hz using this frequency generator. This oscillator can be used as the front end of circuits that require precision pulses.
A crystal is used in the circuit to generate clock pulses. The circuit uses two counter ICs CD4060 and 7490 to divide the basic frequency to generate 50Hz or 60Hz pulses.
