Assume that for each character code we add an odd parity bit as the most significant bit. What are the 8-bit code values for the phrase "Digital Design" (without the quotes) with the added parity bit?

Answer #1

The phrase is "Digital Design".

Odd parity bit is added to ensure that the total number of 1's in a number (parity including) must be odd.

For every letter we have a corresponding ASCII value:

Letter Decimal Binary Parity Bit
D 68 1000100 1
i 105 1101001 1
g 103 1100111 0
i 105 1101001 1
t 116 1110100 1
a 97 1100001 0
l 108 1101100 1
D 68 1000100 1
e 101 1100101 1
s 115 1110011 0
i 105 1101001 1
g 103 1100111 0
n 110 1101110 0

These parity bits will be added at the MSB and this will be the 8-bit code value for the letters of the given phrase.

Hope this helps.

(In c code only, not c++) We will simulate the status of 8 LEDs that are connected to a microcontroller. Assume that the state of each LED (ON or OFF) is determined by each of the bits (1 or 0) in an 8-bit register (high-speed memory). Declare a char variable called led_reg and initialize it to 0. Assume that the least-significant bit (lsb) controls LED#0 and the most-significant bit (msb) controls LED#7. In the main function, build and present a...

Consider a noisy communication channel, where each bit is flipped with probability p (the probability that a bit is sent in error is p). Assume that n−1 bits, b1,b2,⋯,b(n−1), are going to be sent on this channel. A parity check bit is added to these bits so that the sum b1+b2+⋯+bn is an even number. This way, the receiver can distinguish occurrence of odd number of errors, that is, if one, three, or any odd number of errors occur, the...

Assignment 2-Case Study-Chapters: 7, 8, 9 & 12 (Macroeconomics) ECON201 Case Study When taxes induce people to change their behavior—such as inducing Jane to buy less pizza—the taxes cause deadweight losses and make the allocation of resources less efficient. As we have already seen, much government revenue comes from the individual income tax in many countries. In a case study in Chapter 8, we discussed how this tax discourages people from working as hard as they otherwise might. Another inefficiency...
