Question # 1

The operation of J-K flip-flop is similar to that of the SR flip-flop except that the J-K flip-flop ___________

Choose an answer

Doesn’t have an invalid state

Sets to clear when both J = 0 and K = 0

It does not show transition on change in pulse

It does not accept asynchronous inputs

(A + B)(A + B + C)(A + C) is an example of ______________

Choose an answer

Product of sum form

Sum of product form

Demorgans law

Associative law

Determine the values of A, B, C, and D that make the sum term A(bar) + B+C(bar)+D equal to zero.

Choose an answer

A = 1, B = 0, C = 0, D = 0

A = 1, B = 0, C = 1, D = 0

A = 0, B = 1, C = 0, D = 0

A = 1, B = 0, C = 1, D = 1

A positive edge-triggered flip-flop changes its state when ________________

Choose an answer

Low-to-high transition of clock

High-to-low transition of clock

Enable input (EN) is set

Preset input (PRE) is set
