a circuit diagram of an electronic device

The Wien Bridge Oscillator is a type of electronic oscillator that generates sine waves. It is widely used in signal generation because of its simplicity and the purity of its output. Here’s a detailed explanation of how it works:---1. Circuit ConfigurationThe Wien Bridge Oscillator consists of:Amplifier: Typically an operational amplifier (op-amp) is used to provide the necessary gain.Feedback Network: A combination of resistors and capacitors (RC network) forms the frequency-selective feedback network.Positive Feedback Path: Provides the phase shift and gain necessary for oscillation.Negative Feedback Path: Stabilizes the amplitude of oscillations.---2. Principle of OperationThe oscillator works based on the principle of a bridge circuit (Wien Bridge), where a specific RC network determines the oscillation frequency. The RC network provides:1. Frequency Selection: The network allows only one specific frequency to pass with the required phase and amplitude.2. Phase Shift: At the selected frequency, the RC ne
