16位右移位寄存器 下面描述的是一个位宽为16位的右移位寄存器，实际具有环形移位的功能，是在右移位寄存器的基础上将最低位的输出端接到最高位的输入端构成的。其功能为当时钟上升沿到达时，输入信号的最低位移位到最高位，其余各位依次向右移动一位。(16-bit right shift register The following description is a right shift register with a bit width of 16 bits. It actually has the function of circular shift. It is based on the right shift register, which connects the lowest bit output terminal to the highest bit input terminal. Its function is that when the rising edge of the clock arrives, the lowest displacement of the input signal reaches the highest position, and the rest of you move one bit to the right in turn.)

说明：  在FPGA实验操作系统实现ASK,FSK,PSK的调制解调，基带信号由M序列发生器产生，经过AD模块在示波器上进行显示，精油DA模块在同一块实验板上进行解调操作，生成信号控制LED灯的亮灭，并与调制输出信号在示波器上同时展示，并进行对比。基带信号为3MHz。(In the FPGA operating system experiment implementation ASK, FSK, PSK modulation and demodulation of the baseband signal generated by the M sequence generator, through the AD module on the oscilloscope display module, oil DA demodulation operation in the same block experiment board, the signal generation control LED lights off, and the modulated output signal displayed on the oscilloscope at the same time, and compared.)
