- Analog communication systems, and
- Digital communication systems.
- An analog communication is a system in which the information signal is transmitted and received in an analog form means a continuously varying signal such as sine wave. Here, both the information and the carrier are analog signals.
- In digital communication, the digital pulses in the form of code words are transferred between two or more points in a communication system.
