Emitter Follower Experiment

Tasks for this lab:

*      Build the circuit below using supplies from the lab, the Instructor, and the Technician.  Use your lab kit from Networks I/II.

*      Test the circuit, and record the voltages at the base and emitter of the transistor when there is no signal applied.

*      Set up your signal generator for a sine wave output

*      Amplitude 1 volt peak

*      Frequency 1,000 Hz

*      Apply the signal generator output to the oscilloscope.

*      Save the plots for your lab report

*      Repeat for a 1 volt peak triangular wave at 1,000 Hz.

*      Repeat for a 1 volt peak square wave at 1,000 Hz.

*      Load the output with a 100 Ohm resistor.

*      Change the frequency of the signal generator to find the high and low frequency limits over which the output amplitude remains approximately constant.

*      Write a lab report.  The lab report is due a week from Monday morning.

Lab Report Instructions and Format


*      The lab report must be a typed report.  Use the equation editor in Microsoft Office for equations.

*      Only one report per group is required.  Each group will have either three or four students.

*      For general principles on structure and style of lab report writing, click here for a 2004 write-up by Mike Campolongo.  Note that the weights and point assignments used are examples and can be used as a guide, but the Instructor will assign weights according to the lab assignment.

Body of report

The body of the report will have the following elements:

*      Objective of the experiment or laboratory.

*      Equipment used, including any software.  Include any schematics and photographs here.

*      Theory behind the experiment, and the approach used in the experiment including how the theory is used in defining the approach.

*      The procedure used in the experiment.

*      What you did.

*      What you saw.

*      What you measured.

Results, Conclusion, and Discussion

*      Measurements, plots, scope curves

*      Refer to the procedure section but do not repeat it in detail.

*      Describe what you learned in the experiment.

*      Explain how the experiment achieved in terms of the objectives.

*      Include other discussion and conclusions as appropriate.

*      End with a summing up and, if appropriate, what you recommend doing next.

All items in the Appendix must be referred to in the body of the report.  If you have material for the Appendix and you can't find an appropriate place in the body to refer to it, either the body is incomplete or this particular appendix material is surplus and should not be included.  Appropriate items for the Appendix include

*      Data tables that are at a level of detail that is inappropriate for the body but are needed to validate the report conclusions.

*      Listings of software such as MATLAB or Mathcad that was used in the experiment.

*      Data sheets for unusual or peculiar hardware or computer utilities that are used in the experiment or its interpretation.

*      Mathematical analysis or derivations that are too detailed for the body of the report.

*      Lists of references or links to Internet sites or pages that support theory or data sheets to support discussions in the body of the report.
