在掌握伪随机序列性质的基础上，设计给定长度的伪随机序列信号发生器，也即设计给定n后（n为移位寄存器的级数）最长线性反馈移位寄存器序列。并在给定n产生的最长序列的基础上，截短出课题给出的序列长度，并用FM软件对可编程器件GAL16V8进 行编程，以实现长度不同的序列信号发生器。-Grasp on the basis of the nature of a pseudo-random sequence, the design given the length of the pseudo-random sequence signal generator, i.e., designed to be fixed after n (n is the number of stages of the shift register) the longest linear feedback shift register sequences. And on the basis of the longest sequence given n generated, truncated topics given sequence length, and the FM software programmable device GAL16V8 programming, in order to achieve a different length sequence signal generator.
