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
Basics
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.
Parts of
the Report

title
Course
name, number and Section (Electronics I, ECE 09-311 Section 1)
Instructor's
name
Names
of Group Members, and Team Name
Date

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.
Appendix
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.
