• _{Lets discuss and describe the Carrier Wave}
• _{RS-232 pin #8 refers to the carrier wave}
• _{the modem generates the carrier wave}
• _{digital data can be represented if a 1 and 0 can be represented via the carrier wave}
• _{what can be changed with regard to the carrier wave (look at the figures on pages 43 and 44 of your text)?}

• _{amplitude modulation of the wave}
  • _{height changes (volume)}
• _{frequency modulation of the wave}
  • _{frequency changes (pitch)}
• _{phase modulation of the wave}
  • _{pattern shift}
