An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current signal.
There are two main types of electronic oscillator: the linear or harmonic oscillator and the nonlinear or relaxation oscillator. 1 MHz electronic oscillator circuit which uses the resonant properties of an internal quartz crystal to control the frequency.
