Answer to Question #56000 in Physics for irebami

Question

The difference between an Oscillator and an Amplifier is that an oscillator
Has More Gain
Requires no Input signal
Requires no DC supply
Always have the same input

Answer 1

The working principle behind the amplifier and an oscillator is different. In an amplifier the output signal is produced only when there is some input signal and a DC power source to increase the energy level of the output. In case of an oscillator, there is no need for the input signal. Here the DC source is the only essential component required.
Answer: b) Requires no Input signal
