Amplitude and Phase Modulation Tutorial Amplitude and Phase Modulation Tutorial Welcome to this comprehensive tutorial on Amplitude Modulation (AM) and Phase Modulation (PM). These fundamental modulation techniques form the backbone of modern communication systems, enabling the transmission of information over various media including radio waves, fiber optics, and wireless networks. 1. Introduction to Modulation Modulation is the process of systematically varying one or more properties of a periodic waveform (called the carrier signal) with a modulating signal that contains the information to be transmitted. This process is essential for efficient communication over long distances. Why Modulation is Necessary Practical Antenna Size: For efficient radiation, antennas need to be at least λ/4 in size, where λ i...
