A signal transmission method in which a transmitter generates a data signal by multiplexing a plurality of pieces of data and transmits the generated data signal to a receiver through a transmission channel and in which the receiver generates a plurality of pulse-width modulation signals corresponding to the plurality of pieces of data in accordance with the data signal includes generating, by means of the transmitter. The data signal in accordance with the plurality of pieces of data such that, at the beginning of each of a plurality of sections of the corresponding pulse-width modulation signals for which logical levels of the corresponding pulse-width modulation signals are set, the logical level of the data signal corresponds to the logical level of the corresponding pulse-width modulation signal for the corresponding section, wherein a transition between the plurality of sections is performed at a different timing for each of the plurality of pulse-width modulation signals; and generating, by means of the receiver, in each of a plurality of systems for generating the corresponding pulse-width modulation signals, the corresponding pulse-width modulation signal by latching the data signal at the beginning of the corresponding section for the corresponding system and holding the data signal until the beginning of the next section for the corresponding system.
