Draw the lead-lag network of Wien bridge oscillator and obtain the expression for its oscillation frequency and required amplifier gain using time domain analysis.
The Wien bridge oscillator is a type of sinusoidal oscillator that uses a combination of a lead-lag RC network and a non-inverting amplifier. Its circuit consists of a series RC network (R₁, C₁) and a parallel RC network (R₂, C₂) connected in a bridge configuration. The output of this network is fed to the input of an amplifier, typically an operational amplifier, which provides the necessary gain to sustain oscillations. The lead-lag network can be represented as ______ _____ ____ ____ ________ ___ _____.
