Signal in Communication | Definition, Types and Characteristics

n a data communication system a signal is basically a physical form of data. The physical layer of the OSI model converts the data in the form of signals. Two nodes in a communication system exchange data in the form of signals.

For example in wireless communication the signal propagation is done via electromagnetic waves also known as radio waves, in optical fiber system the signal is a light wave. Similarly in a computer system signal is an electric current that takes the data from one point to another.

In this signal and systems lecture I will discuss classification of signals. In addition to this I will discuss signal characteristics
