Webscipy.signal.max_len_seq. #. Maximum length sequence (MLS) generator. Number of bits to use. Length of the resulting sequence will be (2**nbits) - 1. Note that generating long sequences (e.g., greater than nbits == 16) can take a long time. If array, must be of length nbits, and will be cast to binary (bool) representation. Web此外，lfsr 可以生成不同长度的输出序列，集体屈居于反馈系数。以下定理将 lfsr 的最大长度定义为其度的函数。 定理：度为\ m\ 的\ lfsr\ 可以产生的最大序列长度为 2^m-1. 这个定理的证明非常简单。lfsr 的状态是由 m 个内部寄存器位唯一确定。
