AM(Amplitude Modulation)调制是一种常见的模拟调制技术,通过改变载波信号的幅度来传输基带信号。在AM调制中,基带信号被乘以一个高频载波信号,产生一个带有两个边带的调制信号。这两个边带位于载波频率的上下方。 FM(Frequency Modulation)调制是一种模拟调制技术,通过改变载波信号的频率来传输基带信号。在FM调制中,基带...

DPCM(Differential Pulse Code Modulation,差分脉冲编码调制)和 DM(Delta Modulation,增量调制)都是模拟信号数字化的方法。DPCM利用样本之间的相关性,对当前样本与预测样本之间的差值进行编码。通过对差值信号进行量化和编码,减少了表示信号所需的比特数。DM是一种简单的一位编码技术,根据当前输入样本与预测样本的差值,决...
