Q3. In a (7,4) Hamming Code, three parity bits p1, p2, p3 are added to four data bits dl, d2, d3, and d4, and the coverage of each parity bit is as shown in the table below: Bit position 2 3 4 5 6 7 Encoded data bits p1 p2 di p3 d2 d3 d4 da X p1 X X X x Parity bit coverage p2 х X X p3 X X X х 1) (3 pts) Assume even parity...

A Hamming code is a technique where errors can not only be detected but can also be corrected. The simplest example of this kind of code is the (7,4)-Hamming code. In this scheme, a codeword is 7 bits long. We number the positions as follows: 1 2 3 4 5 6 7 The message that is sent is only four bits long, with these four bits occupying positions 3, 5, 6, and 7. Bits 1, 2, and 4 are...

5-Given that the ASCII code for A is 1000001, what is the ASCII code for J? Express the answer as 7 binary digits. 6- Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7. We have already calculated that we need 4 check bits, and the length of all code words will be 11. Code words are created according to the Hamming algorithm presented in the text....

1. How many different characters could be encoded using a six-bit code? 2. What is the numerical difference between ASCI a and ASClI 'AN if you treaj them as hexadecimal (hex) numbers? 3. The ASCII codes for the characters 'O' through '9' are what hex numbers? If an asynchronous frame is used to send ASCII characters in the form of bytes (8 bits), what is the shortest time it could take to send 1000 characters if each bit in a...

3. We want to transmit commands to a drone over a wireless channel. The commands and the probability of transmission are as follows: up (0.1), down (0.1), forward (0.4), left (0.15), right (0.15) and hover (0.1). (30) (a) What is a compact binary code to transmit these messages? (5) b) Suppose for hardware simplification reasons, a fixed 4-bit representation of each of the commands is used instead of the compact code. If a command is sent every second, how inefficient...

Implement the Point class (code for this up to the isHigher
method was discussed in the
lecture). The class has the following instance variables:
• x coordinate (an int)
• y coordinate (an int)
and the following methods:
• Constructor that sets the x and y coordinates
• Get and set methods
• Method equals if this point is equal to another point object
(if the x and y coordinates are the
same).
• Method isHigher if this point is...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
