Explanation / Answer

Question No: 1

(a)Determine the decimal value of the signed binarynumber ‘11101000’ expressed in 1’scomplement      flip thebits    00010111 convert to decimal 1+2+4+16=23                 so it's -23                                                        

(b) Convert the gray code ‘10101111’ tobinary   

A. write down the number in graycode
B. the most significant bit of thebinary number is the most significant bit of the gray code
C. add (using modulo 2) the nextsignificant bit of the binary number to the next significant bit ofthe gray coded number to obtain the next binary bit
D. repeat step C till all bits of the gray coded number have beenadded modulo 2
