The output of a 3-input logic circuit f(x, y, z) is 1 if ax + by + cz < d and 0, otherwise (a, b, c, d are constant). For what values of a, b, c, d does this represent an implementation of the AND gate.

The simplification of the Boolean expression (P’QR’)’ + (PQ’R)’ is….

For the circuit shown below find out the canonical form of the output f(A,B,C)

What will be the state of the output after the 3^rd clock to the given circuit.

Assume initially Q_A = 0, Q_B = 0
