Question

Find CRC for P = 110011 and M = 1100011

Answer 1

Answer:

To find CRC is equivalent to find remainder of 2 n M/ P . 1. First need to find n, we can get this from P where P is(n+1)-bit. In our problem P has 6 bits, so n = 3. 2

Answer 2

" CRC is 1110001100000 "

Given:

P = 110011 and M = 1100011

To Find:

CRC

Step by step Explanation:

CRC Stands for Cyclic Redundancy Check. CRC is an error identifying method. It mostly used in digital networks and storage devices to detect accidental error changes to raw data.  

M Stand for Message

P stand for Pattern

Message (M) = 1100011 (8 bits)

Pattern (P) = 110011 (6 bits)

First to find n, we can get n from P  

where, P is (n+1)

In our problem P has 6 bits , so n= 5

There are 5 bits, the message will be multiplied by $2^{5}$ . Append the 5 zeros at the end of message. Finally, the message will become 1110001100000

CRC is 1110001100000
