说明：  昨天刚刚写好的dsb-sc信号生成与解调程序，用离散（dsp）的方法生成DSB信号，载波频率为150khz,音频是500hz和2000hz的混合音，加入SNR=1DB的噪声，用正交解调实现解调，画出解调前后的频谱图，欢迎共同学习，进步。(yesterday just finished the dsb- sc signal generation and demodulation process, discrete (dsp), the signal generated DSB, the carrier frequency of 150kHz, audio is 500Hz and 2000hz mixed audition to join SNR = 1DB of noise, with quadrature demodulator to achieve demodulation, paint around the demodulation spectrum welcome to learn together and progress.)
