The wien bridge oscillator is a type of RC oscillator, that produces the sinusoidal output. It is commonly used in audio and Sub-audio frequency ranges, that is 20- 20KHz. The maximum frequency of the output of a wien bridge oscillator is only about 1MHz. Circuit Diagram explanation of WIEN BRIDGE OSCILLATOR It has two stage RC …
Simplest sinusoidal variable frequency oscillator is amstrong circuit. Simplest sinusoidal constant frequency oscillator is crystal oscillator. Parasitic oscillation is caused by transistor inter electrode capacitance. If you movie towards an oscillating circuit its frequency increases because of hand capacitance. Frequency stability is maximum in wein bridge oscillator. Practically in order to change frequency of oscillation …
