<p><P>PROBLEM TO BE SOLVED: To reduce noise by securing a transmission output to establish communication. <P>SOLUTION: The power superimposed multiplex communication apparatus for a vehicle for superimposing a communication signal subjected to ASK modulation on a DC power on a power supply line and making communication includes a second waveform shaping section 10 that dulls the rising and/or trailing of a rectangular wave communication signal, which is ASK-modulated and transmitted, to thereby provide a prescribed slope to a rising waveform and/or trailing waveform of the transmitted communication signal. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
