Course Coordinator: Victor M. Rooney, Professor 

Goals/Objectives:  

  • To illustrate classroom topics using a hands-on approach to the design, fabrication, and testing of electronic circuitry used to transmit or otherwise process pulse type signals. 
  • Also, the students will acquire a good deal of practical use of computer simulation of network techniques through the use of MICRO-CAP IV. 
    •

    Computer Usage: Extensive use is made of MICRO-CAP IV throughout this experiment as described above in the introductory paragraph to the LABORATORY PROJECTS section. 

    Course topics and lecture hours devoted to each topic:  

  • MICRO-CAP IV is used extensively in this series of experiments. For most experiments the student must simulate, by use of MICRO-CAP, the actual circuit employed. The output of MICRO-CAP produces a time history graph of the resultant transient output pulse from the circuit. The student then manually plots two additional graphs on top of the MICRO-CAP graph, namely a plot taken from the CRO during the experiment, and then a plot derived by the student entirely through mathematical means using classical transient analysis techniques. 
  • Consequently, the student may instantly compare the observed experimental results with the computed theoretical output as well as with the simulated output from MICRO-CAP. 
  • Exp. 7.1 Single Node R-C and R-L Circuits: Requires a CRO, a Pulse Generator, and miscellaneous passive components. Apply pulses of different durations to single node circuits. Compare measured, theoretical, and MICRO-CAP IV results. (1 wk.) 
  • Exp. 7.2 Two Node R-C and R-L circuits: Requires a CRO, a Pulse Generator, and miscellaneous R-L-C components. Apply pulses of different durations to two node circuits. Compare measured, theoretical, and MICRO-CAP results. (1 wk.) 
  • Exp. 7.3 Circuits that have polynomials in the transform: Requires a CRO, a Pulse Generator, and miscellaneous R-L-C components. Apply pulses of different durations to the specified circuits. Compare measured, theoretical, and MICRO-CAP results. (1 wk.) 
  • Exp. 7.4 Damped Circuits: Requires a CRO, a Pulse Generator, and miscellaneous R-L-C components. Investigate the concepts of under-damped and over-damped circuits by application of pulses of various duration to three types of R-L-C networks. Compare measured, theoretical, and MICRO-CAP results. (1 wk.) 
  • Exp. 7.5 Frequency Response of a Circuit: Requires a CRO, a Signal Generator, a Volvmeter, and miscellaneous R-L-C components. Apply sinusoidal signals to several of previously employed circuits to determine their frequency response characteristics. Compare measured, theoretical and MICRO-CAP IV results. (1 wk.) 
  • Exp. 7.6 Frequency Response of a Circuit Using Bode Plot Techniques: Requires a CRO, a Signal Generator, a Voltmeter, and miscellaneous R-L-C components. Experimentally determine the frequency response of three circuits. Perform a MICRO-CAP IV simulation of the same circuits and obtain a frequency response graph. Draw a Bode plot on the MICRO-CAP graph. Also plot the experimentally derived data on the MICRO-CAP graph. Compare the three sets of data. (1 wk.) 
  • Exp. 7.7 Frequency Response of Under-damped RLC Circuits Using Graphical and Bode Techniques:Requires a CRO, a Signal Generator, a Voltmeter, and miscellaneous R-L-C components. In a manner similar to that used in experiment 7.7, compare the Bode plot, the experimentally derived data, and the MICRO-CAP 111 frequency response plot. (1 wk.) 
  • Exp. 7.8 The correlation Between Frequency Response and Time Response: This experiment consists of analyzing data from previous experiments so as to determine the correlation between a circuit’s frequency response and its time response. In particular data from experiments 7.3 and 7.6 will be correlated as will data from experiments 7.4 and 7.7. (1 wk.) 
  • Exp. 7.9 Clampers (DC - Restorers): Requires a Pulse Generator, a CRO, miscellaneous R-L-C components and a silicon diode. Investigate and verify the operation of a Clamper (DC Restorer) circuit. (1 wk.) 
  • Exp. 7.10 The 555 Timer Astable Multivibrator: Requires a DC Power Supply, a 555 integrated circuit, a CRO, and miscellaneous passive components. Investigate the operation and application of the 555 timer in the astable multivibrator mode. (1 wk.) 
  • Exp. 7.11 The 555 Timer Monostable Multivibrator (one-shot): Requires a DC Power Supply, a 555 integrated circuit, a CRO, and miscellaneous passive components. Investigate the operation and application of the 555 timer in the monostable multivibrator (one-shot) mode. (1 wk.)
