Question

Draw a block diagram of generalized communication system​

Answer 1

Answer:

In a communication system, the transmitter is located at one place,  the receiver is located at some other place (far or near) separate from the  transmitter and the channel is the physical medium that connects them.  Depending upon the type of communication system, a channel may be in  the form of wires or cables connecting the transmitter and the receiver or  it may be wireless. The purpose of the transmitter is to convert the message  signal produced by the source of information into a form suitable for  transmission through the channel. If the output of the information source  is a non-electrical signal like a voice signal, a transducer converts it to  electrical form before giving it as an input to the transmitter. When a  transmitted signal propagates along the channel it may get distorted due  to channel imperfection. Moreover, noise adds to the transmitted signal  and the receiver receives a corrupted version of the transmitted signal.  The receiver has the task of operating on the received signal. It reconstructs  a recognizable form of the original message signal for delivering it to the  user of information.
