The source is the originator of the information that
is to be exchanged via the communication system. The source converts the original message information (in voice, text or
image format) into an electrical signal. For voice, the source normally uses a microphone to convert the sound waves
generated by the human speaker into electrical signals. Text is
converted to electrical signals through a teletypewriter or computer; images
are converted through a camera or video camera.
