Attended: Mengyuan, Creighton, Scott

• Updates:
  • Developed an algorithm for real time processing
    • Algorithm will calculate the moving average of the filter
• To Do:
  • Fix usb connection error

• Updates:
  • Continued researching methods of determining propagation time
    • One method is to keep track of the start time (signal sent) and the end time (signal received)
    • Because we don't have a transducer yet to keep track of the start, we will improvise with using two receivers and a source further away, the propagation time being the time between the receivers
  • Started developing an algorithm and circuit to accomplish above
    • The algorithm will use a combination of thresholding and phase shift detection to determine precisely the time
    • Need a Schmitt trigger for counting the wavelength number
      • Found a Schmitt trigger on DigiKey
• To Do:
  • Update parts order list with Schmitt trigger
  • Continue developing algorithm and circuit
