Actual Difference Between Oscillator and Amplifier


Oscillator and Amplifier



The actual difference between Oscillator and Amplifier is, Oscillator can create an oscillating signal and the amplifier can increase the magnitude of an oscillating signal.

So Amplifier comes in use after Oscillator. We already have a complete article on Oscillator which will give you the whole concept of an Oscillator. So you can read that article.

Before going to know the difference, let's discuss something about Oscillator and Amplifier,


Oscillator:



Oscillator input and output


An oscillator is an electrical or electronic circuit which can create the oscillating signal. We can generate the oscillating signal of any frequency, shape using the oscillator circuit. The oscillator takes a steady state signal as input and it gives the oscillating signal as the output.
In the oscillator circuit, phase feedback is must need to stabilize the output. An oscillator circuit can give output after removing the input signal that means it needs the input for a short time.


Applications:


          1. Oscillator circuits are used in computers, laptops, mobiles to generate clock pulses.
          2. Crystal Oscillator is used in Watches.





Amplifier :


Amplifier input and output

An amplifier is also an electronic circuit which can increase the magnitude of the signal. The amplifier can increase the power of an electronic signal. The amplifier needs an auxiliary power supply to increase the magnitude of a signal. An ideal amplifier gives exact same output signal as the input signal, it just increases the magnitude. The amplifier acts as a multiplier of the input signal. The multiplication factor is also depended on the feedback.



Applications:


          1. In the Audio system, amplifiers are widely used. To drive a powerful speaker amplifier is used to increase the magnitude or power of the audio signals.



Oscillator VS Amplifier:



SL
NO.
Oscillator
Amplifier
1.
The Oscillator can create a periodic signal.
The amplifier can increase the amplitude of the Signal.
2.
The oscillator needs the input for a short time that means the oscillator can give the output signal even after removing the input signal.
The amplifier does not give the output if the input signal is removed.
3.
The Oscillator acts as a source of a signal.
The amplifier acts as a multiplier of a signal.
4.
Applications:
Oscillators are used in computer, laptops etc to create the clock pulses.
Applications:
Amplifiers are used in audio systems to increase the magnitude of the audio signal.
