<p><P>PROBLEM TO BE SOLVED: To provide a method for achieving modulation and demodulation for a radio transmission line that can be achieved at low costs that are the same or lower than those of a transmission line by an electrical wire, such as conventional copper for constructing the radio transmission line at a close range, such as the inside of the same casing, and by low power consumption; and to provide a reliable transmitter, a receiver, and electronic equipment at low costs and with low power consumption. <P>SOLUTION: There are provided a periodic signal generation means for generating a periodic signal containing at least a harmonic component, a modulation means for modulating a signal generated by the periodic signal generation means by a transmission signal, and a transmission means for extracting the harmonic component from the output signal of the modulation means. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
