An LC oscillator is an electronic circuit that generates oscillating signals using an inductor (L) and a capacitor (C). These components store energy in magnetic and electric fields, respectively, allowing the circuit to produce a continuous waveform, typically a sine wave. The frequency of oscillation depends on the values of the inductor and capacitor, following the formula f = \frac12\pi\sqrt{LC} . LC oscillators are commonly used in various applications, including radio transmitters, signal generators, and frequency synthesizers. They are valued for their ability to produce stable and precise frequencies, making them essential in communication and electronic systems.
