An oscillator is nothing but an amplifier with

A transistor oscillator is (i) an amplifier with positive feedback (ii) an amplifier with reduced gain (iii) the one in which dc supply energy is converted into ac output energy . Then

i) An amplifier is necessarily an oscillator too ii) An oscillator is necessarily an amplifier too Then

A transistor oscillator is (i) An amplifier with positive feedback (ii) An amplifier with reduced gain (iii) The one in which DC supply energy is converted into AC output energy. Then

A transistor oscillator is (i) An amplifier with positive feedback (ii) An amplifier with reduced gain (iii) The one in which DC supply energy is converted into AC output energy. Then

Open loop gain of an amplifier is A. If a feedback oscillator is made by this amplifier then what feedback ratio is to be taken?

What is an amplifier?
