I/P msg : It is the desired msg or information to be transmitted.
I/P Xducer : It is used to convert i/p source from any form to electrical quantities example : micro phone.
s/g conditioning : These units are used to condition the s/g. Example : amplifier, filter, etc.
Electronic Xmitter : It is used to transmit the s/g or couple the s/g to the channel.
CN Channel : It is used to propagate information from source to destination.
CN Channel : It can be broadly classified into wired and wireless cn.
Electronic Rvr: It decouples the info. s/g to the recover system.
o/p msg : It is information or message s/g received back.
Info source & I/P Xducer : It is the desired info to be transmitted in digital format. sampling is to be performed.
Source Encoder : It is used to perform encoding of the data, it removes redundancy from the data. Example: Huffman coding.
Channel Encoder : It is used to make s/g compatible to travel on CN Channel.
Digital modulator & demodulator : They assured for digital systems to modulate & demodulate digital data.
Channel Decider : It is used to remove the redundancy added during channel encoding.
Source Decoder: It is used to reconstruct data by adding redundancy back.
Noise: It is an unwanted electrical phenomena that affects the s/g.
