MATLAB-based 2FSK Modulation and Demodulation M-file Implementation

This MATLAB-based 2FSK modulation and demodulation M-file is a script file written in MATLAB programming language that implements the complete 2-Level Frequency Shift Keying (2FSK) modulation and demodulation process. The implementation utilizes MATLAB's built-in functions and custom algorithms to perform signal processing operations including carrier wave generation, frequency shifting, signal mixing, and detection mechanisms. The code typically employs key MATLAB functions such as sin() for carrier generation, logical operations for signal mapping, and FFT-based frequency analysis for demodulation. This M-file serves educational, learning, and research purposes, helping users gain deeper understanding of digital modulation principles, signal processing techniques, and communication system implementation. The implementation may include features like adjustable carrier frequencies, configurable sampling rates, and visualization of modulated signals and demodulation results using MATLAB's plotting capabilities.
