Communication systems
Electronic communication refers to the faithful transfer of informationor message (available in the form of electrical voltage and current)from one point to another point.
Transmitter, transmission channel and receiver are three basic unitsof a communication system.

Transducer: Any device that converts one form ofenergy into another can be termed as a transducer.
Signal: Information converted in electrical form and suitable for transmission is called a signal. Signals can be either analog or digital.
Noise: Noise refers to the unwanted signals that tend to disturb the transmission and processing of message signals in a communication system.
Transmitter: A transmitter processes the incoming message signal so as to make it suitable for transmis sion through a channel and subsequent reception.
Receiver: A receiver extracts the desired message signals from the received signals at the channel output.
Attenuation: The loss of strength of a signal while propagating through a medium is known as attenua tion.
Amplification: It is the process of increasing the amplitude (and consequently the strength) of a signal using an electronic circuit called the amplifier.
