Name: __________________________________ Modeling of Biomedical Engineering Systems BME 348 (14220, 14223, 14224): Final Exam - KEY May 16, 2011 Questions 1-50 are multiple choice. Each question is equally weighted and valued at 2 point. For each question, circle the one answer that you think is most correct. Circle your answer on the Exam sheet AND bubble in your selected answer on the Scantron. Calculators are NOT allowed when working the Exam. 1. If the source voltage ( v s ) input into the operational amplifier above is v s =-0.01volts, then the output voltage ( v out ) will be: A. 1 volt B. 10 volt C. -1 volt D. -10 volt E. None of the above 2. Consider a linear system model of the pupil control system that we discussed in class. If light incident on the eye is switched on and oscillates at 1Hz, the response of the pupil (according to the model) can be described by A. A pure 1Hz oscillation B. A step response superimposed on a 1Hz oscillation C. Unpredictable oscillations D. A step response E. None of the above 3. If the magnitude of the feedback transfer function (k) is much less than the open- loop response (|k| << |H o |) , the algebraic expression for the closed loop response will closely approximate, QUESTION DROPPED

Name: __________________________________ 4. If the magnitude of the feedback gain (|kH o |) is much greater than unity (|kH o |>>1), the algebraic expression for the closed loop response will closely approximate, 5. If the open-loop transfer function is H o =c 1 s and the negative feedback transfer function is k=c 2 /s, the closed loop transfer function will approximate: 6. When the left ventricle of the heart ejects blood, the aorta expands 2ml for a pressure increase of 50mmHg, the capacitance of the aorta is: A. 25 mmHg/ml B. 0.04 ml/mmHg C. 100 ml · mmHg D. None of the above 7. Consider the concentration of the enzyme-substrate complex [X] in an enzyme substrate reaction. If the enzyme concentration [E] is increased and all other concentrations unchanged, the rate of formation of the enzyme-substrate complex will,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
