Linear Integrated Circuit Frequency Generator

A linear integrated circuit function generator contains a voltage-controlled oscillator (VCO). It is a free-running oscillator with a stable frequency of oscillation that depends on a timing capacitance, a timing resistance and an external control voltage. The output from a VCO is a frequency and its input is a bias or control signal that can be either a DC or an AC voltage. In this experiment, the operation of an XR-2206 linear integrated circuit function generator has been examined. In the GUI frequency generator, users can change the timing resistor and capacitors to vary the output frequency. The oscillator produces two wave shapes, square and sine.
