Crc calculation method
______________*_____________________
This is the topic consern with BE btech studendt
let take a simple example.
Let's do a simple example, dividing a message 100110 by the
key 101.
100110 = x^5 + x^2 + x (why i have writen this.count from
left threr is 6 numrix value so it sholud start frrom x5
and last is x^0
simalry 101 is x2 + 1.(it is key value with degree 2 max
degree)
Since the degree of the key is 2, we start by appending two
zeros to our message.
10011000 / 101
101
111
101
100
101
100
101
01
We don't even bother calculating the quotient, all we need
is the remainder (the CRC), which is 01 in this case. The
original message with the CRC attached reads 10011001. You
can easily convince itself that it is divisible by the key,
101, with no remainder.
In practice we don't write the top bit of the key--it is
implicit. In this particular example, we would only store
bits 01 as our key.
