An electronic oscillator is a circuit that generates a repetitive electronic signal, often in the form of a sine wave, square wave, or triangle wave. These signals are crucial in various applications, including radio transmission, audio equipment, and clock generation in digital circuits. The basic components of an oscillator typically include an amplifier and a feedback loop. Oscillators can be classified into two main types: linear oscillators and non-linear oscillators. Linear oscillators use passive components like resistors and capacitors to create oscillations, while non-linear oscillators rely on active components like transistors. Both types play essential roles in modern electronics.
