Description: MASK译码器设计代码MASK调制方式是采用多电平基带信号对一个高频载波进行平衡调制，得到多种幅度的高频已调波。它在频谱上是载波抑制的双边带信号，单侧边带的带宽等于基带信号本身的带宽，所以整个已调波带宽是基带信号带宽的二倍。 《通信原理》的课程设计-MASK code decoder design MASK modulation is multi-level baseband signal to a balanced high-frequency carrier modulation, has been a variety of high-frequency range has been transferred wave. Its spectrum is suppressed-carrier signal with bilateral, single side-band bandwidth base-band signal equivalent to their own bandwidth, so the whole tune-wave base-band bandwidth is twice the signal bandwidth.
