| Abstract: | The analog modulation and demodulation principle in communication is illustrated briefly.The analog modulation and demodulation system based on NI LabVIEW 8.5 software platform was designed and developed.The signal such as amplitude signal,double sideband signal,single sideband signal,vestigial sideband signal and so on can be observed real-timely through this system.The simulation result is analyzed.The design system can be applied to signal and communication teaching and experiment course,deepen students′ understanding and mastering of the courses in science and engineering so as to enhance the teaching level and quality. |
