Description
“Mini Hardware” problem. Design a circuit that will allow you to connect the line-out of a portable
music player to the unipolar ADC on our K22F boards. Your design must utilize only parts/components
that are available in our parts shop. I have seen both active and passive solutions to this problem. Your
write up for this problem should include your design process, calculations, steps, as well as a full circuit
schematic (including chip pin connections, etc.). Once your design is done, wire up your circuit to ensure
it functions correctly. Jeff Erickson can provide you with a breadboard panel and parts. We will make
use of this circuit in later assignments.
To check off this portion of the assignment, have the following set-up before class on Friday, October 16:
play your choice of audio on a music device, run this audio through your circuit to the ADC on the K22F,
run the digital wire code, and put the output to a speaker. You should be able to hear your (most-likely
aliased) music.
