All Modulation Types Explained in 3 Minutes

In this video, I explain how messages are transmitted over electromagnetic waves by altering their properties—a process known as modulation. Check out my blog for an introduction to this video: https://www.wirelessexplained.com/wha... We'll explore: The Basics of Modulation: Understanding how amplitude, phase, and frequency are used to encode information. Analog vs. Digital Communication: How messages in analog and digital formats are modulated differently. Modulation Techniques: Analog Modulation: Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM). Digital Modulation: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). Real-World Applications: Learn where these modulation schemes are used, from traditional radios to modern cellular networks. QAM Modulation: Learn why Spectral Efficiency is important, hence QAM modulation is used for its high spectral efficiency. ▬ Contents of this video ▬▬▬▬▬▬▬▬▬▬ 0:00 - Introduction 0:20 - Properties of Electromagnetic Waves: Amplitude, Phase, Frequency 0:37 - Analog Communication and Digital Communication 0:56 - Encoding message to the properties of the carrier waves 1:05 - Amplitude Modulation (AM), Phase Modulation (PM), Frequency Modulation (FM) 1:38 - Amplitude Shift Keying (ASK), Phase Shift Keying (PSK), and Frequency Shift Keying (FSK) 2:06 - Technologies using various modulation schemes 2:24 - QAM (Quadrature Amplitude Modulation) 2:42 - High Spectral Efficiency of QAM 3:07 - Converting Analog messages to Digital messages by Sampling and Quantization My name is Anver Hisham, and I hold a PhD in Wireless Communication.
