OVERVIEW
• Design and create a Four Channel Ultrasonic Receiver,
capable of receiving signals between 30 kHz and 50 kHz.
• Capable of receiving a chirp signal as well as a constant
frequency signal (Beacon).
• Will work with Team B’s Ultrasonic Transmitter.

TESTING/EVALUATION
• Will design the system one component at a time,
simulating each environment.
• Function generators will be used to simulate incoming
signals and oscillators.
• We will slowly integrate each component to another,
making sure each stage is designed properly.
• An important aspect of our testing is to verify that the
synchronization circuit between Team B’s transmitter is
working properly, since that is primary use for our
receiver.
• Once everything is verified we will get with Team B and
test the chirp and beacon signals.

RISK MITIGATION
High risks:
1. High volume of components
2. Maximum Voltage/Current ratings of components
3. Micro-solder required (most components will be surface
mount)
4. Maximum ratings of the Arduino Due
5. Avoid component interference
6. Collaboration amongst team members and with the
transmitter team is crucial.
