Introduction to Analog Communication Notes

Analog Communication is a technique via which different types of information such as images, videos or electrons can be sent from a transmitter to a receiver, utilising signals of continuous nature. Analog systems are highly tolerant to noise; it makes fair use of bandwidth, and are simple to manipulate mathematically. Analog signals require hardware transmitters and receivers that are built to fit the particular transmission ideally. Operating on a new system, and choosing to improve the analog signal, one needs to change the transmitters and receivers completely.
