✅作者简介:热爱科研的Matlab仿真开发者,修心和技术同步精进,matlab项目合作可私信。 🍎个人主页:Matlab科研工作室 🍊个人信条:格物致知。 ⛄ 内容介绍 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...
DDS实现AM调制、DSB调制【Matlab】【FPGA】【Vivado】【信号处理】【通信原理】【软件无线电】 一、为什么要调制 调制(modulation)就是对信号源的信息进行处理(低频),加到载波上(高频),使其变为适合于信道传输的形式。 无线电传输时,频率越高,波长越小,发射时需要的天线也越短。 式中,λ为波长(m);c为电磁波...

语言: Matlab 标签: pam 高速下载 资源简介 脉冲振幅调制(Pulse Amplitude Modulation)是脉冲载波的幅度随基带信号变化的一种调制方式。若脉冲载波是冲激脉冲序列,则抽样定理就是脉冲振幅调制的原理。而实际上,由于真正的冲激脉冲串不能实现,通常只能采用窄脉冲串来实现。
