Transfer Functions By: John Getty Laboratory Director Engineering Dept. University of Denver Denver, CO Purpose: Identify and verify circuit transfer functions and practice transfer function design. Equipment Required: • 1 - Agilent 54600B Oscilloscope (Replacement model: Agilent DSO6012A Oscilloscope or Agilent DSO5014A 5000 Series Oscilloscope) • 1 - Agilent 34401A Digital Multimeter • 1 - Agilent 33120A Function Generator (Replacement model: Agilent 33220A Function / Arbitrary Waveform Generator) • 1 - Protoboard • 1 - 1-k Resistor • 1 - 0.01-μF Capacitor Various Passive Components Prelab: Review the sections in Ch. 9 * covering pole-zero diagrams and the sections in Chs. 10 and 11 covering transfer functions and transfer function design. 1. Transfer Function Analysis The circuit of Fig. 1 is a first-order RC circuit with the output v out (t) taken across the capacitor. The input is the unit step function v in (t) = u(t). 1) Determine the circuit voltage transfer function T V (s), the step response transform G(s) and the output waveform g(t) for v out (t) as indicated in Fig. 1. b. Enter the circuit of Fig. 1 into a CCA program and determine the step response by performing a transient analysis. Plot the results and tape the output into your lab journal. 2. Transfer Function Design 1

### What students are saying

• 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.
