Function Generator Circuits

A function generator is an electronic device that can be used to produce various different waveforms over a range of frequencies. Some of the most common waveform types produced by function generator circuits are sine, square, triangular and sawtooth. 


How do function generator circuits work?

A basic function generator circuit produces a triangular waveform at a frequency that can be controlled. The triangular wave is used as the base for all of the circuit's other outputs, which are generated by charging and discharging a capacitor (used to store electric charge) to shape the waveform. As the output voltage reaches an upper or lower limit, the charging or discharging is reversed by a comparator (a device used to compare two electrical signals). Different frequencies can then be achieved by varying the size of the capacitor and charge current, as well as the frequency of the base triangular wave. 


What are function generator circuits used for?

Function generator circuits are typically used to test analog devices such as amplifiers and communications equipment.
