Telephone Communication
One of the simplest devices in your house
Microphone – converts sound energy of voice into electrical energy (encodes)
Wires – the electrical energy travels from your phone, via exchanges, to your friend’s
Receiver – friend’s earpiece speaker converts the electrical energy back to sound
Answering Machine – friend isn’t home, and this machine stores your communication
Play Button – friend gets home, presses play, hears your recorded voice

ASSIGNMENT 2 – Example
Radio:
Goal: Inform Persuade Entertain Control Manage Educate
Source: Sounds and Information
Encoder: Devices convert sound and info into modulated sine waves
Transmitter: Antennas radiate the radio waves into air (medium)
Receiver: Antennas capture the radio waves from air
Decoder: Devices convert radio waves back into sounds and data
[Storage: Recording devices store sounds and data for playback]
[Retrieval: Stored data can be accessed and played]
Destination: Consumers’ ears and eyes
