调制波 - 百度百科
Modulation Wave. 信号调制，就是一个数学运算，载波是一个正弦波，它有几个参数，幅度、频率、相位。. 用一个携带信息的信号去改变载波的某一个或几个参数，信号就被调制到载波上。. …
Modulation involves multiplying the input signal x(t) by a cosine with a frequency f2. Demodulation involves multiplying the modulated signal again by a cosine with a frequency f2, and then …
