Parity check codes with even parity can be viewed as linear block codes. Consider the Following situations: a. One parity check bit (even parity) is appended to three data bits. Write down the generator matrix and the parity matrix for this linear block code. b. 2-D even parity for a block of data: di d2 P1 dz d4 P2 P3 P4 Ps where d;'s are the data bits and p;'s are the parity check bits for the rows and the columns. Write down the generator matrix and the parity check matrix for this code. How many errors can it correct? How many errors can it detect?

[8.2] Calculate the product of -8.0546875 x 10° and -1.79931640625 × 10¹ by hand, assuming A and B are stored in the 16-bit half-precision format (1 for sign bit, 5 for exponent, and 10 for fraction). Assume there is a guard, a round bit, and a sticky bit, and use them if necessary. Show all the steps. Indicate if there is overflow or underflow. Write your answer in both the 16-bit floating-point binary format and as a decimal number. How accurate is your result? How does it compare to the number you get if you do the multiplication on a calculator?

Can you do number 2 for me please
