This laboratory manual is carefully coordinated to the text
Electronic Devices, Tenth edition, Global edition, by Thomas L.
Floyd. The seventeen experiments correspond to the chapters in the
text (except the first experiment references Chapters 1 and the
first part of Chapter 2). All of the experiments are subdivided
into two or three "Parts." With one exception (Experiment 12-B),
the Parts for the all experiments are completely independent of
each other. The instructor can assign any or all Parts of these
experiments, and in any order. This format provides flexibility
depending on the schedule, laboratory time available, and course
objectives. In addition, experiments 12 through 16 provide two
options for experiments. These five experiments are divided into
two major sections identified as A or B. The A experiments continue
with the format of previous experiments; they are constructed with
discrete components on standard protoboards as used in most
electronic teaching laboratories. The A experiments can be assigned
in programs where traditional devices are emphasized. Each B
experiment has a similar format to the corresponding A experiment,
but uses a programmable Analog Signal Processor (ASP) that is
controlled by (free) Computer Aided Design (CAD) software from the
Anadigm company (www.anadigm.com). These experiments support the
Programmable Analog Design feature in the textbook. The B
experiments are also subdivided into independent Parts, but
Experiment 12-B, Part 1, is a software tutorial and should be
performed before any other B experiments. This is an excellent way
to introduce the ASP technology because no other hardware is
required other than a computer running the downloaded software. In
addition to Experiment 12-B, the first 13 steps of Experiment 15-B,
Part 2, are also tutorial in nature for the AnadigmFilter program.
This is an amazing active filter design tool that is easy to learn
and is included with the AnadigmDesigner2 (AD2) CAD software. The
ASP is part of a Programmable Analog Module (PAM) circuit board
from the Servenger company (www.servenger.com) that interfaces to a
personal computer. The PAM is controlled by the AD2 CAD software
from the Anadigm company website. Except for Experiment 12-B, Part
1, it is assumed that the PAM is connected to the PC and
AnadigmDesigner2 is running. Experiment 16-B, Part 3, also requires
a spreadsheet program such as Microsoft (R) Excel (R). The PAM is
described in detail in the Quick Start Guide (Appendix B).
Instructors may choose to mix A and B experiments with no loss in
continuity, depending on course objectives and time. We recommend
that Experiment 12-B,Part 1, be assigned if you want students to
have an introduction to the ASP without requiring a hardware
purchase. A text feature is the Device Application (DA) at the end
of most chapters. All of the DAs have a related laboratory exercise
using a similar circuit that is sometimes simplified to make
laboratory time as efficient as possible. The same text icon
identifies the related DA exercise in the lab manual. One issue is
the trend of industry to smaller surface-mount devices, which are
very difficult to work with and are not practical for most lab
work. For example, almost all varactors are supplied as surface
mount devices now. In reviewing each experiment, we have found
components that can illustrate the device function with a
traditional one. The traditional through-hole MV2109 varactor is
listed as obsolete, but will be available for the foreseeable
future from Electronix Express (www.elexp.com), so it is called out
in Experiment 3. All components are available from Electronix
Express (www.elexp.com) as a kit of parts (see list in Appendix A).
The format for each experiment has not changed from the last
edition and is as follows: * Introduction: A brief discussion about
the experiment and comments about each of the independent Parts
that follow. * Reading: Reading assignment in the Floyd text
related to the experiment. * Key Objectives: A statement specific
to each Part of the experiment of what the student should be able
to do. * Components Needed: A list components and small items
required for each Part but not including the equipment found at a
typical lab station. Particular care has been exercised to select
materials that are readily available and reusable, keeping cost at
a minimum. * Parts: There are two or three independent parts to
each experiment. Needed tables, graphs, and figures are positioned
close to the first referenced location to avoid confusion. Step
numbering starts fresh with each Part, but figures and tables are
numbered sequentially for the entire experiment to avoid multiple
figures with the same number. Conclusion: At the end of each Part,
space is provided for a written conclusion. Questions: Each Part
includes several questions that require the student to draw upon
the laboratory work and check his or her understanding of the
concepts. Troubleshooting questions are frequently presented. *
Multisim Simulation: At the end of each A experiment (except #1),
one or more circuits are simulated in a Multisim computer
simulation. New Multisim troubleshooting problems have been added
to this edition. Multisim troubleshooting files are identified with
the suffix f1, f2, etc., in the file name (standing for fault1,
fault2, etc.). Other files, with nf as the suffix include
demonstrations or practice using instruments such as the Bode
Plotter and the Spectrum Analyzer. A special icon is shown with all
figures that are related to the Multisim simulation. Multisim files
are found on the website: www.pearsonglobaledition.com/Floyd.
Microsoft PowerPoint (R) slides are available at no cost to
instructors for all experiments. The slides reinforce the
experiments with troubleshooting questions and a related problem
and are available on the instructor's resource site. Each
laboratory station should contain a dual-variable regulated power
supply, a function generator, a multimeter, and a dual-channel
oscilloscope. A list of all required materials is given in Appendix
A along with information on acquiring the PAM. As mentioned,
components are also available as a kit from Electronix Express; the
kit number is 32DBEDFL10.
