FSK Modulation Program Implementation

Following our previously uploaded FSK demodulation program, this submission provides the corresponding FSK modulation implementation. Both programs belong to the Communication Principles system simulation series, specifically designed to help MATLAB beginners understand digital communication systems through practical code examples.

This MATLAB program implements Frequency Shift Keying (FSK) modulation, where digital data is transmitted by shifting between two distinct carrier frequencies. The code typically involves generating a carrier signal, creating a binary data sequence, and switching between frequencies based on the input bits (e.g., frequency f1 for binary '1' and f2 for binary '0'). Key functions may include sine wave generation using sin(2*pi*f*t), logical switching operations, and proper sampling rate configuration for accurate signal representation.

While this program is ready for use, we recommend that beginners study the code structure and modulation principles before implementation. The implementation demonstrates important concepts like frequency separation, modulation index calculation, and time-domain signal generation. Should you encounter any issues or have questions about the algorithm or MATLAB syntax, please don't hesitate to ask for clarification. We hope this practical example enhances your understanding of digital modulation techniques!
