For the purposes of studying discrete channel coding, we can view the combination of digital data modulator, channel, and digital data demodulator as simply a discrete channel. In general in information theory, there are no fixed rules on exactly where the channel starts and stops, and therefore it is always appropriate to regard the channel as the part of the system (excluding the source) which we do not care to change at the moment.
