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:
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.
