Analog Communication

Analog communication is a method of transmitting information using continuous signals. It is based on the principle of varying the amplitude, frequency, or phase of the signal to carry data. Unlike digital signals, analog signals are infinitely variable and can represent a wide range of values. Examples of analog communication include traditional telephone systems and AM/FM radio broadcasting.

Digital Communication

• Digital communication is the transmission of information using digital signals instead of analog signals.

• It offers higher quality and greater reliability compared to analog communication.

• Examples of digital communication include email, text messaging, and internet telephony.

• Advantages of digital communication include error correction and encryption for secure transmission.

• It has revolutionized the way we communicate, enabling instantaneous and global connections.
