Cards (14)

  • What bounces back from the atmosphere and can reach rural areas?
    Amplitude Modulation
  • What just passes through the ionosphere meaning it can only reach nearer areas?
    Frequency modulation
  • What is also called the transducer, where sound waves are converted to electrical signals, and these signals are fed to the modulator?
    Microphone
  • What modifies if it's going to be AM or FM (audio or video info)?
    Modulator
  • What generates fixed frequency (carrier waves-sound waves)?
    Oscilator
  • What increases the energy carried by the wave?
    Amplifier
  • What converts to electrical waves?
    Broadcast anthena
  • This picks up all the frequency.
    Receiving anthena
  • What selects the frequency received?
    Tunner circuit
  • What feeds the audio to loud speaker?
    Demodulator
  • What strengthens the received signals?
