ABSTRACT:
A modulation/demodulation apparatus includes a modulator for modulating data. When a central processing unit is operating in a first operating mode, a changeover unit selects and outputs modulated data signals provided by the modulator. When the central processing unit is operating in a second operating mode, the changeover unit selects and outputs unmodulated data signals. An IR light emitter outputs IR light corresponding to the data signals selected and output by the changeover unit.
