Hi.

I'm studying about LFSR recently, but there is some problem.

This is 3-bit LFSR and my book said that this circuit is expressed by primitive polynomial of p(y)=y^3+y+1

I thought that Y3's value is y and next Y3's value is p(y). But after I have calculated it, I saw it was wrong.

So, I have substituted each Y1 to Y3 values to y but it doesn't shows any relative value to Y1 to Y3.

What is p(y) and y's actual meaning in LFSR? Is it related to any value of each DFF's output?
