OscillatorsAn oscillator is a type of electronic circuit that is used to generate a periodic, repetitive signal. Oscillators are commonly used in a wide range of applications, including telecommunications, audio systems, and control systems. There are many different types of oscillators, including crystal oscillators, RC oscillators, and LC oscillators, which use different types of components to generate the oscillating signal. Oscillators are an essential component of many electronic systems, as they provide a reference signal that can be used to synchronize other circuits or devices.
