This is the book, in which the subject matter is dealt from elementary to the advance level in a unique manner. Three outstanding features can be claimed for the book viz. (i) style; the student, while going through the pages would feel as if he is attending a class room. (ii) language: that an average student can follow and (iii) approach: it takes the student from ''known to unknown'' and ''simple to complex.'' The book is reader friendly, thought provoking and stimulating. It helps in clearing cobwebs of the mind. The style is lucid and un-adulterated. Unnecessary mathematics has been avoided.

Basic Concepts and Signal Analysis

A significant point about communication is that it involves a sender (transmitter) and a receiver. Only a receiver can complete the process of communication. Therefore dual process of “transmitting and receiving” or “coding and decoding” an information can be called as communication; thus, this is a two way process.

1.1 COMMUNICATION

As a general concept, we can say that transfer of information from one place to another is communication.

The important elements of a communication system are:

1. Message or information
2. Sender, transmitter or coder
3. Receiver or decoder
4. Code
5. Channel (transmission path)

1.2 METHODS OF COMMUNICATION

The communication may be:

• (a) Oral Communication: In this type of communication, the message is sent or transmitted from the sender to the receiver through spoken words e.g., direct talk or through telephone. The communication through hints or face expression also come under this category.
• (b) Written Communication: When the message is sent to the receiver in writing, it is called written communication, e.g., communication through letter, FAX etc.

1.3 PROCESS OF COMMUNICATION (SEE FIG. 1.1)

The process of communication involves the following steps:

1. Encoding the message: The encoder for transmission encodes the message into suitable words, symbols etc.
2. Transmission: After developing the message into suitable code, it may be transmitted through a proper channel.
3. Reception: The information is received on the other side by the receiver.
4. Decoding: The coded message is decoded into the original form, so that it is easily understood by the person on the receiver side.

5. Use: The final stage of the communication process is to use the information for the purpose, it has been transmitted.

In earlier days pigeons were used to send message (Information, signal) from one place to anothe...
