Resource Overview
FM modulation implemented using Simulink with 13KHz carrier frequency and 3KHz frequency deviation. The modulated waveform is saved as a waveform file. FM demodulation employs dual-slope frequency discrimination sampling technique, with demodulated signal directly output to sound card.
Detailed Documentation
This implementation demonstrates FM modulation using Simulink, where the carrier frequency is set to 13KHz and the frequency deviation configured as 3KHz. The modulated waveform is saved as a waveform file for further analysis or playback. In the demodulation process, the system utilizes dual-slope frequency discrimination technique for sampling, which involves comparing the phase differences between consecutive signal cycles to extract the original modulating signal. The demodulated output is directly routed to the sound card for real-time audio playback, utilizing Simulink's audio sink blocks for hardware interfacing. The model incorporates key Simulink blocks including sine wave generators for carrier signal, frequency modulators with configurable deviation parameters, and custom subsystems implementing the dual-slope detection algorithm for accurate frequency demodulation.
