K-map Truth Table Quiz

A 3-variable K-map has a minimal expression A'B + BC. What could be a possible truth table representation for this function?

• The minterms are (000, 010, 011, 111).

• The minterms are (010, 100, 110, 111).

• The minterms are ( 010, 011, 110, 111).

A 3-variable K-map has a minimal expression A'BC + AB'. What could be a possible truth table representation for this function?

• The minterms are (001, 010, 100, 111).

• The minterms are (000, 011, 101, 110).

• The minterms are (010, 011, 101, 111).

A K-map has minterms m(0,1,2,3,8,9,10,11). What is the simplified Boolean expression?

• B'C' + BC'.

• BC' + BC.

• BC' + B'C.

A 4-variable K-map has a grouping forming a circular wrap-around (edge adjacency). How does this affect the simplification process?

• It increases the number of variables in the Boolean expression.

• It prevents further minimization due to edge boundaries.

• It allows further simplification by considering opposite edges as adjacent.

• It results in a redundant Boolean expression.

A 4-variable K-map contains two separate groups of four 1s each, located in different quadrants. What does this indicate about the simplified Boolean expression?

• The expression will have exactly four variables.

• Each group will contribute a separate term in the simplified expression.

• The groups must be combined into a single term.
