Explanation: the expression for absorption law is given by: a+ab = a.
Explanation: the demorgan’s law states that (ab)’ = a’ + b’ & (a + b)’ = a’ * b’, as per the dual property.
Explanation: maxterm is the sum of terms of the corresponding minterm with its literal complemented.
Explanation: minterm is given by 2n. so, 23 = 8 minterms are required.
Explanation: sop expressions can be implemented using either (1) 2-level and-or logic circuits or (2) 2-level nand logic circuits.
Explanation: there are 16 = (24) cells in a 4-variable k-map.
Explanation: the given expression a +a’ = 1 is based on non-impact unifying theorem.
Explanation: in a minterm, each variable w, x or y appears once either as the variable itself or as the inverse. so, the given expression satisfies the property of sum of minterm.
