一、概述 通过FPGA实现AM信号的产生与解调。要求是通过VIO控制载波频率、调制信号频率、调制深度可调,然后通过ILA观察AM信号和解调后的信号。载波信号的频率要求是1M~10M,调制信号的频率要求是1K~10K,调制深度从0到1、步进0.1。VIO与ILA只能通过硬件板卡实现。 二、平台 软件:Vivado 2017.4 硬件:ALINX ZYNQ AX7020 三、要求 为了更好的说明下面一些参数设定的意义,把我们课程的部分要求贴上来 完成AM信号调制和解调功能,具体要求如下: (1)载波信号频率范围:1M-10MHz,分辨率0.01MHz; (2)调制信号为单频正弦波信号,频率范围:1kHz-10kHz,分辨率0.01kHz; (3)调制深度0-1.0,步进0.1,精度优于5%; (4)调制信号和解调信号位宽为8位,AM信号16位,其他信号位宽自定义。 四、原理 虽然这部分简单,但却是最最重要的,把这部分看懂,所有的程序也就明白了。 1.
