An RC oscillator is an electronic circuit that uses a combination of resistors (R) and capacitors (C) to produce a periodic, oscillating signal, usually in the form of a sine or square wave. Unlike oscillators that use inductors, RC oscillators are more suitable for generating low-frequency signals and are commonly used in audio frequency applications, timers, and signal generators. The frequency of the oscillation is determined by the values of the resistors and capacitors in the circuit. RC oscillators are valued for their simplicity, low cost, and ease of integration into digital and analog systems. They are less suitable for high-frequency applications due to limitations in component performance.
