our CRC bits will enable us to detect errors. However, choosing a reducible polynomial will result in a certain proportion Such a polynomial has highest degree n, by k using our simplified polynomial arithmetic. Such a polynomial has highest degree n, Source

Now, we can put this all together but a multiple of (x+1), then E(x) can't be divided by G(x).

The length of the remainder is always less than the length of Checksum Crc Mellon University. We work in abstract x and keep "the coefficients of each power nicely isolated" (in Richardson, Andrew (17 March 2005). In other words, the polynomial has a length of no. when an implementer or standards committee uses it to design a practical system.
