Communication Basics
The process of data transfer from one person to another person is called communication. All the living organisms in the earth communicate. If two persons are far away (they are not near with respect to each other), then the message from one person needs to be modulated and transmitted to the other person. For doing like this it requires one transmitting antenna and one receiving antenna. The message from one person will be encoded, modulated and transmitted to the other through a transmitting antenna. The receiving antenna will collects the transmitted signal and it decodes the encoded data. The way of communication con be either one sided (example T.V, radio etc) or two way communication (Mobile phones).
The communication may be either analog or digital communication.
Analog means we are transmitting the signal in the analog form.
Digital communication means we are transmitting the signal in the digital form.
The communication may be either analog or digital communication.
Analog means we are transmitting the signal in the analog form.
Digital communication means we are transmitting the signal in the digital form.
