Abstract: A communication system is configured to use a pulse width modulation signal as transmission code among a plurality of nodes connected to a communication line. A master node includes a transmission transistor connected to the communication line, a detector configured to detect a variation in current during the on-period of the transmission transistor, and a communication circuit configured to determine the off-timing of the transmission transistor based on the timing of occurrence of the variation in current (i.e., the on-timing of a second transmission transistor provided in a slave node). For example, the communication circuit can be configured to determine the off-timing of the transmission transistor such that the simultaneously-on period TB of the transmission transistor and the second transmission transistor fulfills TB=(2n?1)/2f, where f is the frequency of EMI noise.
