Objectives of this experiment:
1. To construct a wein-bridge oscillator and determine the resistor ratio required to develop the correct degenerative feedback.
2. To insert a simple automatic gain-control and observe the effect on oscillator operation. 3. To vary the values of resistance and capacitance In the lead-lag network and to observe the resultant frequency changes.
To construct wein bridge oscillator using RC combination, usually preferred for low frequency application. A lead lag R-C network determines the oscillator frequency and controls the amount of regenerative feedback for the oscillator. Degenerative feedback is set by a resistance voltage divider.
