【Abstract】 In accordance with the principle of 2ASK modulation and demodulation,a graphical simulation of 2ASK Digital Communication System based on the Virtual Instrument Lab VIEW software is realized. The simulation structure of the software is introduced in detail. The simulation results of the input sequence and 2ASK signal waveform and output sequence are observed. The results show that the program performs well and the simulation results are right. It indicated a new way to analyzing and observing communication system in teaching and experiment.更多还原
