Transistor Capacitor Oscillator. Collpitts oscillator is generally used in rf applications and the typical operating range is 20k h z to 300m h z. The relaxation oscillator circuit we will build with a transistor and resistor and capacitor is shown below.

A standard 465 khz if transformer t1 intended for transistor circuits is the lc resonant tank circuit in this oscillator. Actually any voltage from 12v 15v will work. It basically converts direct current from a power supply to an alternating current signal.
All oscillators under different names have similar function i e.
A transistor can be operated as an oscillator for producing continuous undamped oscillations of any desired frequency if tank or oscillatory and feedback circuits are property connected to it. An audio frequency am signal fed to the emitter of q1 through blocking capacitor c2 will modulate the supply voltage of q1 and thus amplitude modulate the circuit s 465 khz carrier signal. They generate continuous undamped output. Oscillator is an electronic circuit that produces a periodic oscillating signal often a square wave and a sine wave.
