All Modulation Types Explained in 3 Minutes

In this video, we dive into 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 Music: Erik SATIE - Gymnopedies 1 #modulation #communicationsystems #communicationsystem #wirelesscommunication #amplitudemodulation #frequencymodulation #AM #fm #electromagneticwaves #transmitter #transmission #AnalogAndDigitalCommunication #lte #4g #5g #6g
