序列信号为1101000101的序列产生器

一种可能的序列产生器是以下的线性反馈移位寄存器(LFSR):
```
1 -> 1 -> 0 -> 1 -> 0 -> 0 -> 0 -> 1 -> 0 -> 1
```
这个LFSR有10个位,初始状态为`1001101110`。每次时钟周期,LFSR将右移一位,同时将第1位和第4位的值异或后作为新的最后一位。因此,前几个时钟周期的输出如下:
```
1001101110 (初始状态)
0100110111
1010011011
1101001101
1110100110
0111010011
1011101001
1101110100
0110111010
1011011101
1101101110
```
可以看到,这个LFSR的输出序列确实是1101000101。
