This is a group project
which will require working with another student. The project is a design
project using Multisim with the requirements given below. The project is due on
the last day of the term.
Total
Points: 100
Project
name: Audio Amplifier (Multistage)
Audio
Amplifier Power Output selection: 3.2 W, 5.6 W, 7.1 W, 8.4 W, 11.5 W, and 16.3 W
Audio
Amplifier Input Voltage (peak) selection: 150mVpeak, 200mVpeak, 250mVpeak
Audio
Frequency: 20 Hz – 20 KHz
Deliverable: Multisim design (soft copy), test results,
short report, and teamwork evaluation
Project
Definition:
Design, simulate, and
test an Audio Amplifier which delivers one of the above power outputs to an 8?
speaker load. The output power of your design and the input signal of your
design must be selected from the above list. The audio frequency range is
between 20 Hz to 20 KHz, so the operating frequency of your design will be
within this range. The measuring equipment should display the output power and
the input signal of your design. You are required to use either or both NPN and
PNP transistors, but not an op-amp. It is recommended that you use multistage
amplification of any class amplifiers of your choice. You should try to
minimize your usage of components and be cost effective.
Project
Structure:
In general, you will
have one other classmate in your team. Each of you will design and simulate an
audio amplifier with different specifications, each making your choice from the
above parameters. Thus, it is highly suggested that you communicate with your
partner as early as possible to plan and coordinate your activities, select the
input voltage and output power for your design, and establish a schedule. For
the testing phase, you will develop a test plan and characterize and validate
your teammate’s amplifier.
During the project
period, you are encouraged to communicate, exchange ideas, and help each other
complete your project. A team area will be set up for you in Blackboard, and
you are required to use this area as part of your grade will be based on
effectively using this tool.
Project
Deliverable: Report and the
multisim design for your project
Each student will submit
an individual report. The report should, as a minimum, include the following:
·
Title Page (Name,
Partners name, like the table they have in the document)
·
Description of your
project (including the specifications you selected)
·
Design methodology
(show calculations and provide rationale for design choices; remember that your
choices must take into consideration commonly available parts)
·
Final schematic in
Multisim
·
Components/Parts list
with cost and total project cost
·
Simulation results for
your design
·
Testing process and
results for characterization and validation of your teammate’s design –
screenshots along will not suffice. Description of process is required along
with discussion of results.
·
Project Challenges:
Note any difficulties you faced during the completion of your design and how
you overcame them
·
Team Interaction
Reflection: Describe how you used Blackboard to facilitate interaction, how you
worked with one another in the design phase, challenges you encountered,
methods you employed to overcome any challenges.
·
Teammate Assessment:
Use the Project Participation Rubric below and give your teammate a ranking of
Needs Improvement, Competent, or Excellent for the first two items in the
rubric: Interacts professionally and Plans and organizes team effort. Be sure
to justify your ranking.
