The Wien Bridge Oscillator is an electronic circuit used to generate sine waves. It consists of a combination of resistors and capacitors arranged in a specific configuration, allowing it to produce stable oscillations at a desired frequency. The circuit is known for its simplicity and effectiveness in generating low-distortion waveforms. This oscillator operates on the principle of positive and negative feedback. By adjusting the resistance in the circuit, the frequency of the output signal can be fine-tuned. The Wien Bridge Oscillator is commonly used in audio applications and signal processing, making it a valuable tool in electronics and engineering.
