Given the following circuit: What function is implemented by Y2?

Given: A basic 3:8 decoder has address inputs A2:0 and outputs Y0, Y1, …, Y7. Suppose A2 = 1, A1 = 0 and A0 = 0.  Select the correct answer.

Given: F(A,B,C).  Which of the following is the minterm of F that corresponds to A=0, B=1, C=0?

Given the following circuit: If the inputs are E=0, A=0 and B=1, what is the value of Y?

A timing diagram is given for inputs to a D Flip-Flop with Enable (active high). What is the value of the Q output of the D Flip-Flop with Enable at time = 11 ns? Assume the delay from inputs changing to output changing is negligible.

Given the following circuit: What function is implemented by Y2?

A truth table with four output functions is given. Function Y1 will be implemented using a 4:16 decoder that has address inputs A3:0 and outputs Y0, Y1, …, Y15.  Which outputs need to be connected to an OR gate to produce function Y1 (do not confuse function Y1 with output Y1 on the decoder)? 

Given the following circuit: If the inputs are E=0, A=0 and B=1, what is the value of Y?

How many D flip-flops are needed to represent 11 different states?

A timing diagram is given for inputs to a D Flip-Flop with Enable and Reset (both active high, reset is synchronous). What is the value of the Q output of the D Flip-Flop with Enable and Reset at time = 13 ns? Assume the delay from inputs changing to output changing is negligible.
