Abstract: A modulation module includes a first modulation circuit that, upon receiving input of first setting information including first information designating a modulation mode, outputs a prescribed auxiliary signal as a first output signal, but upon receiving input of second setting information including second information designating a different modulation mode from the first information, outputs a first modulation signal generated by subjecting an input signal to modulation processing based on the second setting information as the first output signal. The modulation module further includes a second modulation circuit that is configured to output, as a second output signal, a signal generated by combining a second modulation signal generated by modulation processing and the first output signal.

Abstract: A correction circuit including: a first selector and a second selector that each select and output either of a first input signal or a second input signal, the first input signal and the second input signal having phases that are orthogonal to one another; a first multiplier carrying out multiplication of an output of the first selector and a first coefficient; a second multiplier carrying out multiplication of an output of the second selector and a second coefficient; a first adder carrying out addition of the first input signal and a multiplication result of the first multiplier; and a second adder carrying out addition of the second input signal and a multiplication result of the second multiplier, wherein an addition result of the first adder and an addition result of the second adder are outputted from a first output terminal and a second output terminal, respectively.

Abstract: On receipt of a first frame, each of a plurality of communication devices transfers the first frame through a second port in a case in which it has recognized itself as not being a first communication device based on first information, and does not transfer the first frame in a case in which it has recognized itself as being the first communication device. On receipt of a second frame, each of the plurality of communication devices transfers the second frame through the first port in a case in which it has recognized itself as not being a second communication device based on second information, and does not transfer the second frame in a case in which it has recognized itself as being the second communication device.

Abstract: In a battery monitoring system, when a communication interface circuit receives an output command for monitoring data of each cell according to an instruction from a battery management circuit, the output commands are simultaneously transmitted from a third connection port and a fourth connection port of the communication interface circuit to both of a first connection port of a group and a second connection port of the group in a battery pack unit group, communication control is performed such that the output commands are transmitted to all of plural battery pack units, and communication data output from each of the plural battery pack units is output from both of the connection ports.
