What is Communication?
As we understand that the Communication is simply the basic process of exchanging information. The electrical devices which are used for communication purposes are known as communication equipments. Different types of communication equipments when assembled together form a communication system.
Analog communication involves the transmission of information using continuous signals that vary in amplitude, frequency, or phase to represent data. Unlike digital communication, which discretizes data into binary code, analog communication maintains the original form of the signal throughout transmission.
Key Terms of Communication
Lets see some key terminologies which will help us to understand the concept better.
- Amplitude: The strength or magnitude of a signal, often representing the loudness or intensity of sound in audio communication. It refers to the greatest deviation from equilibrium that an item in periodic motion might display.
- Frequency: The rate at which a signal oscillates, determining the pitch of sound or the channel bandwidth in radio communication. Also frequency is the number of times an alternating current (AC) switches between positive and negative in a unit time.
- Modulation: It is a conversion process used to improve the signals generated from different info sources as they are not always suitable for direct transmission.
- Demodulation: It is an opposite of Modulation as we can define it as the process of reverse conversion for getting the original information or required signal from a modulated carrier signal.
- Noise: Noise can be defined as the unwanted signal that comes along with the message signal and carrier which affects the clarity and reliability of communication.
Introduction to Analog Communication
Communication is the process of establishing a connection or link between two or more points for the exchange of information. Analog communication had a significant need for centuries as it has been a fundamental need of human interaction, which allows anyone with the continuous transfer of signals along with information. Let’s explore the basic principles, essential terminologies, applications, advantages, and limitations of analog communications in this article.
Whoever wants to understand how these communications systems work then it is required to first understand the fundamentals of analog communications. As we have seen a vast development of digital communications, still analog communications are very beneficial in almost every sector as everything around us is in analog form, including television, radio, broadcasting equipment, and telecommunications.
