Study the circuit below,

i. Generate the Boolean expression that describes output D.

D=_______________________________________________

ii. Re-draw the combinational logic circuit given in question 5 in Circuitlab. Connect appropriate DC voltage sources to inputs A, B and C to represent the logic levels A=1 B=0 C=0. 5 Volts should represent an input of 1 whereas 0 V represents a binary input value of 0. Connect a voltmeter to the output of the circuit to display the voltage at output D. Simulate the circuit (run DC solver) and display the voltage value displayed on the voltmeter. Print your circuit clearly showing the voltage obtained on the voltmeter.
