  • Brandon Wilgor
  • Peter Ralston

2
Project Overview
  • Uses Voice Recognition Stamp Board to receive
    commands
  • Analyzes the input command and compares to
    wordbank
  • Determines remote control task corresponding to
    wordbank command
  • Sends code to an external microcontroller
  • Transmits IR signal to the televisions receiver

IR Signal Standard
  • Uses RC5 Frame Format
  • Bit patterns interpreted by Bi-phase coding

6
Modulating the RC5 Square Wave
  • Signal is modulated at a specific frequency by
    the IR transmitter
  • IR receiver demodulate the signal back into
    square wave
  • Noise is rejected by this process
