Communication is the basic process of exchanging information. Analog Communication, as the name suggests is the subject which deals with the techniques employed in communication and basically analog in nature. It is a common knowledge that understanding digital communication is impossible if one does not have a knowledge in analog communication methods. The techniques employed in the subjects are highly useful for engineers and helps them to arrive at effective solutions and to cater to the ever growing demands of the telecom industry. The subject covers a wide range of topics for the knowledge of students and gives them a brief idea about what to do and how to do when dealing with a market full of humans wanting everything at every moment. The subject basically deals with the different aspects of a signal and spectra. It also deals with the modulation of signals and systems and different mathematical aspects related to signals. It gives a more analytical look into the basic entities such as those of signals, modulation, noise etc. which form the base for higher studies in telecommunication.
