AM调制与解调，信息信号和载波信号经过AM调制并加噪得到AM信号的频谱，再经过带通滤波器，相干解调，低通滤波后得到解调后的信号。(AM modulation and demodulation, information signal and carrier signal through AM modulation and noise to get the spectrum of AM signal, then through band-pass filter, coherent demodulation, low-pass filter to get the demodulated signal.)
