Oscillators

Oscillators are electrical circuit components that generate a continuous periodic signal with an amplitude that depends on external or internal components. The output of an oscillator is typically a sinusoidal or a square wave, and is usually used to create an oscillating voltage output when connected to an external source. In electronic circuits, oscillators are used to generate a signal of a specific frequency and are often used in radio communication systems. One of the most common oscillator circuits is the 656L15553I2T oscillator, which is used in a variety of applications, such as radio communication systems, audio applications, and industrial automation.
