This video lecture is about the Frequency Shift Keying (FSK). Introduction to Digital Modulation Techniques has has been given. Block Diagram of FSK modulator has been drawn and explained. There are two types of FSK Demodulation techniques:
(1) Asynchronous FSK Demodulation (Non-coherent detection)
(2) Synchronous FSK Demodulation (Coherent detection)
Block Diagram of Asynchronous FSK Detector & Synchronous FSK Detector have also been explained in detail. Advantages, Disadvantages & Applications of FSK have also been explained.
