The Backbone of Modern Communication
Signals play a vital role in the world of communication and technology. Whether it's the internet, mobile phones, or satellite systems, signals are the invisible threads that connect the world. But what exactly is a signal, and how does it function in our daily lives? What Is a Signal? A signal is a medium that carries information from one point to another. In communication systems, signals can exist in two primary forms: Analog Signals : Continuous waves that vary in amplitude and frequency to represent data. Examples include radio waves and traditional telephonic audio. Digital Signals : Discrete binary values (0s and 1s) used to transmit data in modern technologies like computers and smartphones. How Signals Work in Communication Signals are the foundation of any communication system. They enable the transmission of voice, video, and data across long distances. Here's how the process typically works: Encoding : Information (like a voice or video) is converted into a signal....
