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 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.

	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 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.
