Modems - ICs and Modules: Revolutionizing Communication Technology
In the world of digital communication, modems (short for Modulator-Demodulator) play a crucial role in enabling data transmission over telephone lines, cable systems, and wireless networks. Over the years, modems have evolved from simple devices designed to connect computers to the internet to complex, high-speed communication solutions that enable a wide range of applications. This article will explore the principles, types, and applications of modem ICs and modules, showcasing their significance in modern electronic systems. What Are Modems? Modems are devices that convert digital data from a computer into analog signals for transmission over communication lines, and vice versa. They perform two primary functions: Modulation : Converting digital signals into analog signals for transmission over telephone lines or radio waves. Demodulation : Converting received analog signals back into digital data that a computer or device can understand. These device...
