In an oscillator, for sustained oscillations, Barkhausen criterion is `Abeta` equal to (A = voltage gain without feedback and `beta` = feedback factor)

In a feedback oscillator,

The voltage gain of an amplifier with 9% negative feedback is 10 . The voltage gain without feedback will be

The voltage gain of an amplifier with 9% negative feedback is 10 . The voltage gain without feedback will be

The voltage gain of an amplifier with 9% negative feedback is 10. The voltage gain without feedback will be :-

For sustained oscillation the product of gain of amplifier (A) and feedback factor ( beta ) is

In oscillator feedback circuit is used to minimise

In a negative feedback amplifier, the gain without feedback in 100 , feed back ratio is 1//25 and input voltage is 50 m V . Calculate (i) gain with feedback (ii) feedback factor (iii) output voltage (iv) feedback voltage (v) new input voltage so that output voltage with feedback equals the output voltage without feedback.
