Introduction to Oscillators

Oscillators are electronic components used within a wide range of devices and applications. They use a repeated signal, generally an electrical current, to control processes such as timing, frequency, and phase generation. In some cases, they function as signal sources for control systems used to adjust voltage, current, frequency, and timing fluctuations within an electrical circuit.The most common type of oscillator is an electromechanical resonator such as crystal oscillators. These are mechanical devices used to create a vibration at a certain frequency. They are commonly utilized in timekeeping systems like clocks and watches, as well as in a range of communications systems including television, radio, and cellular phones. Oscillators can also be implemented as electronic circuits, typically made up of various active components like transistors, integrated circuits, and capacitors.
