This online tool draws and analyzes digital circuits which generate Linear Recursive Sequences (LRS) based on a defining polynomial P(x). A complete state table is derived for the sequential circuit shown below.
Circuit based on P(x) = x2+x+1
THIS STATE | ⇒ | NEXT STATE | ||
0 0 | 0 | ⇒ | 0 0 | 0 |
0 1 | 1 | ⇒ | 1 0 | 2 |
1 0 | 2 | ⇒ | 1 1 | 3 |
1 1 | 3 | ⇒ | 0 1 | 1 |
Modulo 2 addition is shown schematically equivalent to Exclusive-OR gates. |
