an oscillator is associated with an basic amplifier for
producing oscillations,for production of oscillations the
amplifier needs some input voltage but under the oscillation
condition the input voltage is zero,why?
Answer Posted / mahadev pawase
I/p voltage is not practically zero.When power on feedback
circuit gives large gain AB > 1 . Originally i/p comes to
the oscillator i/p from feedback and amplifier
circuit.Firstly noise from resistor is the i/p to oscillator
circuit.
