NOTE: Experiments starting with "B" are from Boylestad. "D" and "K" indicate Doutt and Kerckhoff labs which are provided by the instructor.

Each person in EET118L will design and build his or her own circuits, and write his or her own laboratory report. Reports in EET118L should

consist of the following parts (please pay attention to order):

REPORT CONTENTS

1) COVER PAGE -- Must be on UNLINED WHITE paper, TYPED.

Contains:

a) Your name

b) Your class and section (IE., EET118L 3DP)

c) Experiment Title

d) For: SR. PROFESSOR WHEELER

e) Due Date of report (Week # or date given in class)

f) Statement: "This is the original work of <your name>".

( Sign below.)

g) FINAL sign-off blank.

2) LAB PAGES - The original pages from the lab manual, filled out with

data, waveforms, etc.

3) RECORDED DATA PAGES - Where required by the experiment. Some

experiments may require that you produce tables, graphs, etc. that

are not part of the original lab pages.

GENERAL GUIDELINES FOR RECORDING DATA

* All graphs must be done on the appropriate type of GRAPH PAPER.

Frequency response plots should employ SEMI-LOG paper; other plots

should use LINEAR (grid) paper.

* Graphs requiring iterative (repetitive) measurements must have a

DATA TABLE. The data table should be on the page IMMEDIATELY BEFORE

each graph. Data tables must be typed. A SAMPLE CALCULATION for ONE

ROW of the data table must be shown on the same page as the table.

* Oscillograms may employ electronic graphing means (BENCHLINK, for

example); however, the presentation must be clearly labeled.

* All graphs and tables must be APPROPRIATELY TITLED.

=-=-= GRADING =-=-=

Each report in EET118L is worth 100 points; there are 10 reports due, for

a total of 1000 points in the course.

Each report must contain a OPERATIONAL sign-off for credit. A sign-off is provided by the instructor or other authorized person. Performance of each critical portion of the experiment vs recorded data will be verified prior to sign-off.

The instructor reserves the right to use one or more periods for LAB QUIZZES. Students should expect to attend all lab sessions and be prepared for any quizzes. Lab quizzes will increase the total number of points possible. Each quiz, if given, will be worth 100 points.

Letter grades are assigned as follows:

Letter Grade Percentage % Quality Of Work

----------------------------------------------------------

A 90 - 100% Far above average

B 80 - 89 % Above average

C 70 - 79 % Average; meets expectations

D 60 - 69 % Below expectations

F < 60 % Inadequate, failing

*** POLICIES ***

I. LAB PARTNERS

There are NO lab partners allowed in EET118L. EACH PERSON IS EXPECTED TO

WRITE HIS/HER OWN REPORT. All circuits must be CLEARLY ENGRAVED ON TOP with

your name to obtain a sign-off. (Engrave all breadboards prior to

assembling circuits upon them.)

II. LAB SUCCESS HINTS

The successful student will have all circuits built and ready to test

BEFORE going to lab. Lab handouts and other information distributed in

class are extremely important, and should be studied and understood before

attempting the experiment. Try a "dry run" in your mind the day before the

experiment to see if you can recall the important steps, setups, and results. SAVE ALL LAB HANDOUTS, YOU WILL NEED THE INFORMATION FROM THEM ALL TERM!

III. LATE WORK

NO late work is accepted. Work may only be turned in directly to the

instructor during the assigned laboratory period. "Late work" is defined as

work turned in after the end of the assigned lab period during which the

work was due. DO NOT TURN ANY WORK INTO ROOM 208.

IV. PLAGIARISM, AND OTHER FORMS OF CHEATING

Copying the work of another, and claiming it to be your own is PLAGIARISM.

This includes copying others homework, copying from a lab manual or textbook, or copying from another persons report.

All cases involving academic dishonesty will be documented and processed in accordance with the procedures in the Student Handbook. The minimum penalty is a grade of zero for the element involved.

V. MISCELLANEOUS INFORMATION

EMERGENCY PROCEDURES - There are plaques located in the lab discussing

emergency procedures. The instructor will remain in charge of your class

group in an emergency situation.

FOOD - DRINK - Are not allowed in the laboratory at any time, due to safety concerns, even in closed containers of any type. Violators will be expelled from the laboratory, with a grade of zero recorded for the work to be performed in that lab period. Repeat offenders will be suspended from the course with a grade of *F*.

RECORDED DATA

Recorded data consists of GRAPHS, WAVEFORM MEASUREMENTS, and TABLES.

GRAPHS visually represent data, and are generally accompanied by a data TABLE.

For example, the following data table could be used to graph the V -vs- I

characteristic for a resistor:

TABLE I. V vs I for a 1 K Resistor

Current

V(measured) I(measured) I(theory) % Difference

------------------------------------------------------

1 1.05 mA 1.00 mA 5%

2 2.10 mA 2.00 mA 5%

3 3.12 mA 3.00 mA 4%

4 4.20 mA 4.00 mA 5%

.

.

.

I(theory) = V(measured) / R(nominal) = 1 V / 1 K = 1.00 mA

I(meas) - I(theory) 1.05 mA - 1 mA

% Difference = ------------------- X 100% = -------------- X 100% = 5 %

I(theory) 1 mA

NOTE that every table has a TITLE (Here, "Table I ..."), and where appropriate,

a set of SAMPLE CALCULATIONS. The sample calculation demonstrates how one case

(row) of the table was calculated.

One or two GRAPHS could be generated from the data in this table. For graphs,

the following should be kept in mind:

* The graph will have a graph number and title; i.e., "GRAPH 1: V vs I for a

1 K resistor."

* The independent variable will be on the horizontal axis. In this case,

the independent variable (the parameter we have control over) is voltage.

* Graph axes will be scaled appropriately and neatly.

* For graphs of frequency response, semi-logarithmic (semi-log) format will

be used: The independent variable (frequency) will have a logarithmic

axis, and the dependent variable will be in decibels (dB) on a linear

axis. Semi-log graphs are used for dB measurements because to compute

a decibel ratio, the log of the ratio must be computed; thus, the vertical

axis is implicitly logarithmic in any graph using dB units.

* No more than two different graphs should be presented on each page of

paper. Ideally, a graph should be adjacent to its data table.

* Computer software should be used to generate graphs where possible; if

you don't know how, sit down with the documentation for your particular

spreadsheet / word processor and learn. It will be time well-spent, for

it's much easier to fix mistakes on a computer-generated graph than one

drawn manually.

WAVEFORM MEASUREMENTS are called for when the instructions say to take

"oscilloscope readings." These are normally a representation of the

oscilloscope "picture" of the waveforms. Like graphs, waveform measurements

are expected to:

* Be appropriately TITLED.

* Have each WAVEFORM LABELED.

* Clearly represent the information.
