-A way to generate a carrier wave -A way to
"add" a signal wave to the carrier wave -An
antenna to radiate the combined waveform -A
"ground" connection to reference the antenna -A
voltage source to drive the transmission
12
Generate a carrier wave
  • Requirements for an oscillator
  • Amplification
  • A frequency determining device
  • Positive feedback
