A communication apparatus time-division multiplexes a first signal transmitted at a first bit rate and a second signal transmitted at a second bit rate which is an integer multiple of the first bit rate, and sends out the first signal and the second signal to one line. The communication apparatus includes a pulse generating unit and a pulse superimposing unit. The pulse generating unit generates repetitive pulses having a width equal to a width of the first signal. The pulse superimposing unit superimposes the pulses generated by the pulse generating unit on the second signal.
