Q1-B-7 points Determine whether the relation D is reflexive, symmetric, transitive, or none and justify your answer: Let D represent the ‘divides’ relation on the set of positive integers   . For all m, n 

Q11-B-8 points Does the following graph have an Euler Circuit? If not, add extra edges to make it an Eulerian Graph. Explain. Set of Vertices V={A,B,C,D,E} Set of Edges E={ AB, AE, AD, AC, BC, BD, BE, CD}.      

Suppose the supply voltage in a digital circuit, VDD, is doubled (VDD is now twice what it was before). If nothing else changed, how does that affect the power consumption?

Given: 101010102  is an 8-bit unsigned binary number. What is its value in decimal (ex: “-25”, “45”)

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

Given: 110011002  is an 8-bit two’s complement number. What is its value in decimal (ex: “-25”, “45”)

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

Given: 100101102  is an 8-bit unsigned binary number. What is its value in decimal (ex: “-25”, “45”)

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

A truth table with four output functions is given. Function Y4 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 Y4 (do not confuse function Y4 with output Y4 on the decoder)?
