Detailed Documentation
I have developed a comprehensive 2FSK modulation and demodulation program designed for better understanding and implementation. The system employs fundamental digital modulation techniques where binary data is transmitted using two distinct carrier frequencies. The modulation module implements frequency shifting through direct digital synthesis (DDS) techniques, while the demodulation section utilizes non-coherent detection methods with envelope detection and threshold comparison algorithms. The package includes auxiliary function programs that handle signal generation, frequency synthesis, and error detection mechanisms, providing a extensible framework for further development in digital communications. Key functions feature parameterized frequency selection, adjustable symbol rates, and built-in visualization tools for waveform analysis.
