The truth table

represents the Boolean function

In the following truth table, V = 1 if and only if the input is valid.

What function does the truth table represent?

Which one of the following expressions does NOT represent exclusive NOR of x and y?

Which one of the following circuits is NOT equivalent to a 2-input XNOR (exclusive NOR) gate?

The simplified SOP (Sum Of Product) form of the boolean expression (P + Q' + R') . (P + Q' + R) . (P + Q + R') is

Consider the following circuit involving three D-type flip-flops used in a certain type of counter configuration.

If at some instance prior to the occurrence of the clock edge, P, Q and R have a value 0, 1 and 0 respectively, what shall be the value of PQR after the clock edge?

Consider the data given in Q50 question. If all the flip-flops were reset to 0 at power on, what is the total number of distinct outputs (states) represented by PQR generated by the counter?

The minterm expansion of f(P, Q, R) = PQ + QR' + PR' is
