Explain why the graph does or does not have an Euler circuit. If it does, specify the nodes within the circuit Figure i: An undirected graph has 6 vertices, a through f. 5 vertices are in the form of a regular pentagon, rotated 90 degrees clockwise. Hence, the top vertex becomes the rightmost vertex. From the bottom left vertex, moving clockwise, the vertices in the pentagon shape are labeled: a, b, c, e, and f.

The following questions pertain to the circuit shown on the previous page. The goal is obtain the current i∆ using nodal analysis. The voltage source common to the two nodes dictates that a supernode must be used. A. What is the dependent source control parameter i∆ in terms of the node voltages? B. Owing to the voltage source between nodes a and b, what is the constraint equation that relates va and vb? (Other than numeric values, your answer should contain only the terms vb and vb.) C. What is the KCL equation for the supernode? (Your equation may contain both va and vb. Or, you are free to use the constraint equation to write the equation in terms of a single node voltage.) Using this equation or the ones previous, what is vb (give a numeric value.) What is i∆ (provide a numerical value).
PRACTICALPERSPECTIVE_ An engineering project managerhas received a proposal from a subordinate who claims the circuit shown could be used as a treble volume control circuit ifR4≫R1+R3+2R2. The subordinate further claims that the voltagetransfer function for the circuit isH(s)=VoVs =−{(2R3+R4)+[(1−β)R4+Ro](βR4+R3)C2s}{(2R3+R4)+[(1−β)R4+R3](βR4+Ro)C2s} where Ro=R1+R3+2R2. Fortunately the project engineer has an electrical engineering undergraduate student as an intern and thereforeasks the student to check the subordinate’s claim.The student is asked to check the behavior of the transfer function asω→0; as ω→∞; and the behavior when ω=∞ and β varies between 0 and1. Based on your testing of the transfer function do you think the circuitcould be used as a treble volume control? Explain.
Design a counter circuit that has 2 inputs X and Y, and one output Z by using “one-hotstate” encoding. When X=1, the circuit counts up or down based on the value of Y; when X=0, the circuit remains in its previous state regardless of the value of Y. When Y=1, the circuit changes states upwards in the order given below and continues this way in a loop. When Y=0, the circuit changes states downwards in reverse order and continues this way in a loop. When the circuit counts upwards, the Z output is 1. The count order : 0, 2, 1, 3
