Multi-Frequency Signaling
I successfully detected binary data in audio signals using FSK modulation. After exploring optimal frequencies and FFT sizes, I achieved a transfer rate of 450 baud. I employed Frequency Diversity and Spread Spectrum techniques for better reliability. Investigated touch-tone telephone frequencies and DTMF signals for modulation. Explored Nyquist Frequency and its impact on signal processing.… Read More
