Analog Communication
Mention any major difference between analog communication and digital communication?
Ans- Analog communication uses analog signals for the transmission of continuous signals to transmit the information, while digital communication uses digital signal whose amplitude is of discrete binary values (0s and 1s). Analog signals are easily affected by noise and quality decreases over distance, while digital signals less affected by the noise and can be easily transmitted.
Why is analog communication still relevant in the age of digital technology?
Ans- Analog communication continues to be relevant due to its simplicity, low cost and smooth signal transmission characteristics. It requires low bandwidth. Many applications, such as voice communication, radio broadcasting, and instrumentation, rely on analog communication for its fidelity.
How does noise affect analog communication, and what techniques are used to minimize it?
Ans- Noise is the unwanted signal comes along with the message signal and carrier which affects the clarity and reliability of communication. It is the random fluctuations that enters the communication system via the communication channel and interferes with the transmitted signal and decrease the quality of a signal while transmission. Its interference can degrade the quality of analog signals, which leads to reduced clarity and reliability. We use filters such as low pass filters, shielding, and modulation for eg frequency modulation to preserve the important signal components.
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.
