an unsigned base 8 number. (10 points)
(C)
If the maximum length of the fractional part is only 8-bit long in a calculator
,what is the error generated when converting 3.1416_10 to binary ? (15 points)
Problem 3 : (25 points)
(A)
Please draw the Karnaugh map of
F(D,C,B,A)= Σm(0,2,3,4,7,8,10) + Σ d(5,12,13,15).
Pleasw note that A is the lease significant bit and D is the most significant
bit. That means ,D'C'B'A corresponds to minterm m_1 while DC'B'A' corresponds
to minterm m_8 .(15 points)
(B)
