Here is a Crystal based pulse generator that gives 50Hz clock pulses from its output. This circuit can be used as the front end of circuits that require precision 50Hz pulses. The circuit uses two ...

When it comes to designing a reliable 50-Hz oscillator, the disadvantage of the good old Wien Bridge oscillator is the difficulty to adjust its own gain. If the gain is higher or lower than the ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...
