Question 41
Consider numbers represented in 4-bit gray code. Let h3h2h1h0 be the gray code representation of a number n and let g3g2g1g0 be the gray code of (n + 1) (modulo 16) value of the number. Which one of the following functions is correct? A: [Tex]g_{0}(h_{3},h_{2},h_{1},h_{0})=\\sum (1,2,3,6,10,13,14,15)[/Tex] B: [Tex]g_{1}(h_{3},h_{2},h_{1},h_{0})=\\sum (4,9,10,11,12,13,14,15)[/Tex] C: [Tex]g_{2}(h_{3},h_{2},h_{1},h_{0})=\\sum (2,4,5,6,7,12,13,15)[/Tex] D: [Tex]g_{3}(h_{3},h_{2},h_{1},h_{0})=\\sum (0,1,6,7,10,11,12,13)[/Tex]

Question 47
Consider the following floating point format
Mantissa is a pure fraction in sign-magnitude form. The decimal number 0.239 × 2
13
has the following hexadecimal representation (without normalization and rounding off :
Question 48
Consider the following floating point format
[caption width="800"] [/caption]
Mantissa is a pure fraction in sign-magnitude form. The normalized representation for the above format is specified as follows. The mantissa has an implicit 1 preceding the binary (radix) point. Assume that only 0\'s are padded in while shifting a field. The normalized representation of the above number (0.239 × 2
13
) is:
