Question

In L- C osccillator amplifier which feed back is used
A. Positive
B. Negative
C. Both
D. None

Answer 1

In L- C osccillator amplifier positive or regenrative feed back is used .

This is because it overcomes the losses its feedback and it generates out frequency without using input signal

Thus Oscillators are self sustaining circuits generating an periodic output waveform at a precise frequency and for any electronic circuit to operate as an oscillator, it must have the following three characteristics.

Answer 2

Answer:

In L- C osccillator amplifier which feed back is used Positive.
