Abstract:
1. A signal transmitter apparatus for transmitting a plurality of N transmission signals generated in synchronization with a first clock signal having a predetermined cycle, via a transmission line including a plurality of N transmission conductors, N being equal to or larger than three, the signal transmitter apparatus comprising: a phase shifter for shifting phases of the transmission signals by predetermined phase shift amounts, respectively, so that the phase shift amounts of the transmission signals are different from each other by 2π/N, to output N phase-shifted signals which are phase-shifted from the N transmission signals; a plurality of N inverters for generating inverted signals of the first to Nth phase-shifted signals, and outputting the inverted signals; and a plurality of N coding transmitters for generating N combined transmission signals and outputting the N combined transmission signals to the transmission conductors, respectively, by combining each of pairs of the phase-shifted signals such that an inverted signal of a first phase-shifted signal is combined with a second phase-shifted signal, when each of the pairs of the phase-shifted signals includes the first and second phase-shifted signals among the N phase-shifted signals and phase shift amounts of the first and second phase-shifted signals are different from each other by 2π/N.
