FOUR CHANNEL ULTRASONIC RECEIVERTEAM CBRIAN MARKUS (TEAM LEAD)DANNY VISELMAN CHEN JIA

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 MITIGATIONHigh risks:1. High volume of components2. Maximum Voltage/Current ratings of components3. Micro-solder required (most components will be surface

mount)4. Maximum ratings of the Arduino Due5. Avoid component interference6. Collaboration amongst team members and with the

transmitter team is crucial.
