<p>There is provided a system for decoding a digital code and in particular a biphase-coded data, by detecting edges of the biphase-code data and the time intervals between edge conditions. A system for decoding the biphase-code data includes a microcomputer 1 to control the system, a remote receiver module (RRM) 3 for logicizing code data received in infrared rays, filtering the waveform, and applying the output to the microcomputer 1; a first remote transmitter (RTTP) 5 for generating Pulse Position Modulation (PPM) code; a second remote transmitter (RTTB) 7 for generating biphase-code according to the pressing of a key; a tuner 9, display unit 11, and servo 13 operated under the control of the microcomputer 1; and a key matrix 15 for entering key data to the microcomputer 1.</p> |
