Question

1) Convert decimal 6,514 to both BCD and ASCII codes. For ASCII, an even parity bit is to be appended at the left. (10 point) 2) Decode the following ASCII code: 1010011 1110100 1100101 1110110 1100101 0100000 1001010 1101111 1100010 1110011 (10 point) 3) The following is a string of ASCII characters whose bit patterns have been converted into hexadecimal for compactness: 73 F4 E5 76 E5 4A EF 62 73 16. Of the eight bits in each pair of digits, the leftmost is a parity bit. The remaining bits are the ASCII code. (a) Convert the string to bit form and decode the ASCII. (b) Determine the parity used: odd or even? (12 point) 4) Convert 0110 0001 0101 1001 BCD to Gray code (10 point)
