Typically, a message produced by a source is electrical in nature, requiring a device called a transducer to convert it into an electrical signal. This quantity varies over time, representing the message as electricity. At the receiving end, another transducer converts the output signal back to the original format. A microphone and speaker are examples of input and output transducers, respectively, in the case of analog messages.
The transmitter attaches the message to the channel in the form of
