信号调制（调幅）与解调的dsp实现，用于dsp5402平台的初学者很有帮助-signal modulation (AM) and demodulation dsp achieved, the platform for beginners dsp5402 helpful

信号调制中的AM调制方法在DSP5402上面的实验，为汇编语言编写，程序已经调通。：）-signal modulation of AM modulation method DSP5402 in the above tests, for the compilation of language, Link procedures have been transferred. :)

调制:将各种数字基带信号转换成适于信道传输的数字调制信号(已调信号或频带信号)。解调:在接收端将收到的数字频带信号还原成数字基带信号. 调制就是将基带信号的频谱搬移到信道通带中或者其中的某个频段上的过程，而解调是将信道中来的频带信号恢复为基带信号的反过程.-Modulation: converts various digital baseband signal to channel suitable for transmission of digital modulation signal (m
