用GAL16V8设计可变长度序列信号发生器，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。(GAL16V8 design variable-length sequence signal generator based on the master pseudo-random sequence nature, the design of a given length pseudo-random sequence Signal generator, designed for the series) up to linear feedback shift register sequences given n (n is the shift register. And given n Sequence length given by the subject on the basis of the longest sequence, truncated, and FM software for programming the programmable device GAL16V8, in order to achieve Different length of the sequence signal generator.)
