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 = 1 ns? Assume the delay from inputs changing to output changing is negligible.

How many D flip-flops are needed to represent 6 different states?

A timing diagram is given for inputs to a D Flip-Flop with Reset (synchronous, active high). What is the value of the Q output of the D Flip-Flop with Reset at time = 1 ns? Assume the delay from inputs changing to output 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 = 1 and A0 = 0.  Select the correct answer.

A truth table with four output functions is given. Function Y2 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 Y2 (do not confuse function Y2 with output Y2 on the decoder)? 

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

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

8. Patient Chart  History and Physical  A 7-year-old is brought to the emergency department after experiencing sudden shortness of breath and swelling around the eyes and lips. The patient recently started a new antibiotic. The child is pale, tachypneic with nasal flaring and grunting. Breath sounds reveal wheezing and stridor.  The assessment reveals urticaria on the chest and arms, weak peripheral pulses, and periorbital edema.             Vital Signs  Heart Rate: 148 bpm  Respiratory Rate: 36 breaths/min  Blood Pressure: 78/44 mmHg  Oxygen Saturation: 88% on room air  Orders  ABGs  Chest X-ray  ECG monitoring  IV access and administration of epinephrine  Oxygen via non-rebreather mask  Nurses Note:   The patient has history of asthma and a known allergy to penicillin.      After identifying the child is experiencing ______________ shock, which action should the nurse perform first?
