Prime objective of this case study is to experiment on Wein Bridge Oscillator. The oscillator is a circuit where a balanced bridge is used because feedback network is Wien Bridge oscillator. The aim of this experiment is to check the operation of the Wien Bridge. To explain this experiment here need some equipment like OpAmp, Trainer Board, Regular power supply, Oscilloscope, Resistor and Capacitor. Here briefly explain procedure of Wein Bridge Oscillator with picture and examples.
