- Based on hamming code (7 , 4) . Given the code 0 1 1 1 1 0 0, if we redid the parity bit generation and all three were wrong, then which data bit was transmitted incorrectly? (d1, d2, d3 or d4?)Consider the example below that shows both the payload and the two-dimensional parity bits (shown in blue), and where exactly one of the payload or parity bits shown has been corrupted. In this example, odd parity is used.A block of bits with n rows and k columns uses horizontal and vertical parity bits for error detection. Suppose that exactly 4 bits are inverted due to transmission errors. Drive a mathematical expression of n and k for the total number of different cases where these 4 error bits will be undetected. Show each important step of your derivation. (Hint: the error bits will be undetected if all the parity bits computed from the block remain unchanged.)
