Introduction
● The purpose of the project was to
demonstrate all the knowledge we have
learned from the beginning of the
semester.
● Groups were told to invent a music source
docking station with a treble and bass
speaker .
● During the entire process lab GTA was
carefully guiding students through each
component of the project
● If students had a good understanding of
the matter the project was not posing
many difficulties
● The process of distinguishing whether a
component is in the right place, gave the
students a greater understanding of the
overall topic of the course

Design Specifications
Bass & Treble:
● Low Pass: Allows lower frequencies to pass through and filters out high
frequencies
● High Pass: Allows higher frequencies to pass through and filters out lower
frequencies.
● Amplifier: Amplifies the input
