Wien Bridge Oscillator

A Wien Bridge Oscillator is a circuit that generates a stable, pure sound or signal without needing an external input once it starts. It uses a combination of resistors and capacitors to create a feedback loop that amplifies a specific frequency. When the circuit reaches the right conditions, it begins oscillating at that frequency continuously. This type of oscillator is commonly used in audio equipment and testing devices to produce accurate, steady signals for analysis or audio playback. It’s valued for its simplicity, stability, and ability to generate a clean tone.
