Abstract:
A receiver circuit is configured to receive a transmission signal represented by a change in DC voltage applied across power supply lines according to transmission data. The receiver circuit is also configured to compare the DC voltage (sampled value(s) of a detection voltage) with a threshold, thereby detecting a change in the DC voltage. The receiver circuit is further configured to calculate the threshold from a voltage value of the DC voltage (the sampled value(s) of a detection voltage) input to a receiver input unit.
