Telephone CommunicationOne of the simplest devices in your house

You speak into the microphone

InputProcesses

Friend hears voice in receiver

OutputEncoderTransmitter

ReceiverDecoderStorage

Retrieval

Microphone – converts sound energy of voice into electrical energy (encodes)Wires – the electrical energy travels from your phone, via exchanges, to your friend’sReceiver – friend’s earpiece speaker converts the electrical energy back to soundAnswering Machine – friend isn’t home, and this machine stores your communicationPlay Button – friend gets home, presses play, hears your recorded voice
