Q1:

For the minterm designation Y = ∑ m (1, 3, 5, 7) the complete expression is

A
Y = A BC + A B C

B
Y = A B C + A B C + ABC + A BC

C
Y = A B C + A B C + ABC + A BC

D
Y = A B C + ABC + A BC + A BC

ANS:B -

Y = A B C + A B C + ABC + A BC

Decimal number 1 = binary number 001 = A BC Decimal number 7 = binary number 111= ABC, Decimal number 3 = binary number 011= ABC Decimal number 5 = binary number 101= ABC . Hence result.
