Journey of Modulation Techniques

  Introduction to Modulation Techniques in Computer Networks What is Modulation? Modulation is a fundamental concept in telecommunications that enables the transfer of data over different types of media, such as cables or airwaves. In simple terms, modulation is the process of altering certain properties of a carrier signal, like its amplitude, frequency, or phase, to encode information. This is particularly useful in computer networks, where data must travel efficiently and accurately from one device to another over various mediums. Imagine you're speaking in a crowded room—you’d naturally change your tone or pitch to ensure you're heard and understood by someone further away. Similarly, modulation helps signals adapt so they can travel long distances without losing the information they carry, ensuring efficient data transmission. Why Modulation is Crucial for Data Transmission In computer networks, data is often in digital form, but not all transmission mediums (e.g., radio w...
