Amplitude Modulation:

                           When the amplitude of the high-frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulation.

Describe amplitude modulation system showing all the fundamental blocks:

  

 Transmitting Antena       

 Master Oscillator  Buffer Amplifies  Harmonic Generator class-C Amplifier Modulator Amplifier Audio Amplifier Microphone



  

1.    Master Oscillator 

    It’s an electronic device that generates carrier oscillation of high frequency. It is an only produce carrier Signal.  

Buffer Amplifies

    A buffer amplifier is one that providers electrical independence terns for motion from one circuit to another.

3.    Harmonic Generator 

    A generator operated under conditions such that it generates strong harmonic along with the fundamental frequency.

     class-C Amplifierfier:

       It takes the signal from Harmonic generator Class –C Amplifier is a means power amplifier. It amplifying the carrier signal maximum times. The amplifying signal which ready to transmitting by the antenna.

Modulator Amplifier

       A modulating amplifier is an only mixer that is mixing two different signals such as carrier signal and audio signal. It is made modulating signal which ready to transmitting by the antenna.

6.Audio Amplifier

 The microphone gives an electric signal to the audio amplifier. The principle work of an audio amplifier is amplifying audio signals. The audio Amplifier gives an output modulating amplifier.

7.Microphone

             The microphone is one type of transducer. It takes sound damaged into electricity. It is the main component to receive the initial audio signal.
