Negative feedback

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.

Distinguish between positive feedback and negative feed back.

What is negative and positive feedback of hormone action?

Assertion : In an oscillator, the feedback is in the same phase which is called as positive feedback. Reason: If the feedback voltage is in opposite phase, the gain is greater than one.

Assertion : In an oscillator, the feedback is in the same phase which is called as positive feedback. Reason: If the feedback voltage is in opposite phase, the gain is greater than one.

Assertion : Positive feedback is essential for converting a transistor into an oscillator. Reason : Positive feedback works between cut-off and saturation region.
