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

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

Suppose the switching frequency in a digital circuit is cut in half (the frequency is now half what it was before). If nothing else changed, how does that affect the power consumption?

PER THE INSTRUCTIONS PROVIDED, ONLY ONE BONUS QUESTION IS GRADED.  IF YOU ANSWER BOTH QUESTONS, ONLY THE FIRST ONE IS GRADED.  Be sure to answer all parts of the question to get full credit! Bonus question option 2: Briefly a) discuss 2 of the ethical dilemma videos we reviewed in class. b) Please be sure to identify the problem and what the accountant or auditor should do.   (Hint:  justify  you think this is the correct path to take in the particular situation)   Ehtical dilemma #1)         Ethical dilemma #2)      

Given:  The size of a memory array is 4K x 18.  How many bits does the RD line have?

A truth table with four output functions is given. Function Y3 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 Y3 (do not confuse function Y3 with output Y3 on the decoder)? 

A timing diagram is given for a 3-bit counter. What is the value of the Q0 output at time = 55 ns?  Assume the delay from inputs changing to outputs changing is negligible.

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 = 9 ns? Assume the delay from inputs changing to output changing is negligible.

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.
