This document outlines the requirements for an audio amplifier group project. Students will work in pairs to design multistage audio amplifiers using Multisim that meet specified power output, input voltage, and frequency range requirements. Each student must simulate and test their own unique design, as well as test and validate their partner's design. Project deliverables include individual reports describing the design process, simulations, testing results, and reflections on teamwork and challenges. Reports will be graded based on design methodology, functionality, testing procedures, management of challenges, writing quality, and teamwork participation.

1. Audio Amplifier Project
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:
150mV
peak
, 200mV
peak
, 250mV
peak
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 8Ω 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

2. 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

3. 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.

PROJECT PARTICIPATION RUBRIC
EXCELLENT
COMPETENT
NEEDS IMPROVEMENT
Interacts professionally with team members – cooperative,
respectful, shares ideas and work load, completes tasks on time
Performs work on time; attends all meetings on time;
participates in timely fashion in asynchronous collaborative
efforts. Listens and responds appropriately. Encourages other
points of view. Openly shares information. Receptive to
feedback. No complaints from any of the team members.
Performs work on time; attends all meetings and participates in
asynchronous collaborative efforts but may be occasionally late
in attendance, providing information or updates. Listens and
responds appropriately. Shares information but may require
prompting. Minimal complaints from other team members.
Is sometimes late in providing information or updates; or may
miss meetings; or shares information but often requires
prompting; or is unreceptive to feedback; or fails to consider
other viewpoints. Numerous complaints from other team
members.
Plans and organizes team effort including roles, work
distribution, and collaboration tools
Actively participates in development of team objectives,
planning, and organization, including roles and tools. Quick to
identify own knowledge and skills applicable to the project and
contributes in assigned role.
Participates in development of team objectives, planning, and
organizing though some prompting may be required. May not
understand the planning phase well but values the process. With

5. help, identifies contribution which can be made and fulfills
assigned role.
May not value the planning and organizing process and the
establishment of roles; or struggles in how to fit into the
project; or depends on others to fulfill assigned role.
