Implementation of Fsk (Frequency Shift Keying) Using Multi-Sim, Matlab, Hardware, and Finding Its Disparities

Abstract This paper presents a comprehensive study of Frequency Shift Keying (FSK) by comparing its practical implementation through Multisim simulation, MATLAB signal processing, and hardware prototyping. FSK is a fundamental digital modulation technique widely used in communication systems. The paper provides historical context, technical background, detailed design procedures, and performance analyses for each implementation method. Practical circuits and MATLAB code are included to illustrate the process. The comparative analysis discusses the advantages, limitations, and appropriate use cases of each method.
