In Class Exercise Error Detection and Correction: Two Dimensional Parity Q1. Su encoded characters) values): ppose that a packet's payload consists of 10 eight-bit values (e.g, representing ten ASciI- shown below. (Here, we have arranged the ten eight-bit values as five sixteen-bit 01010010 00001011 01100110 00110101 00011100 11100111 01000101 00100101 10000111 00011011 the two-dimensional parity (see Figure 5 .5 in the text) bits for each of the five rows and siteen columns assuming odd parity. Assume that the parity bit in the lower right corner is computed so that the parity of the row parity bits in the last row has odd parity. Q2. Now consider the example below that shows both the payload and the two-dimensional parity bits shown in green), and where exactly one of the payload or parity bits shown has been corrupted. In this example, odd parity is used. 01010010 000010111 01100110 001100011 0001110 111001110 01000101 001001011 10000111 000110111 00010101 000110000 Indicate the row and the column location of the bit that has fipped from its original value Q3. Last, consider the example below that shows both the payload bits (in black) and the two- dimensional parity bits (in green), and where exactly two of the payload or parity bits shown has been corrupted. In this example, odd parity is used 01010010 000010111 01100100 001101011 00011100 111001110 01000101 001001011 10000111 000110111 00010101 010110000 Indicate the rows and columns of bits that have been flipped from their original value In this example, is it possible for you to determine the exact location of the bits that have been ft (i.e., to do error correction as well as error detection)
