Abstract
- Dual-channel frequency modulation stereo broadcast system is a typical application of analog modulation technique, FM, double side band with suppressed carrier(DSB-SC), frequency division multiplexing(FDM) and phase-locked loop(PLL) are core techniques. Based on MATLAB/Simulink platform, the auther successful designed a dual-channel frequency modulation(FM) stereo broadcast system.After debugging and testing, the system can work well,system analysis indicates that FDM technique can improve channel utilization, and PLL technique can obtain sub-carrier to demodulate DSB-SC signal.It is worth to reference for related research and performance improvement, and also provide a new exploration to experiment teaching.
