摘要： Disclosed herein is a power supply device including: a position detection signal output section configured to output a position detection signal to a line allowing a current flow in only one direction in response to an order to output the position detection signal from a power supply managing device connected to a bus line including the line; a position detection signal detector configured to detect the position detection signal that is output from another device and flows through the line; and a position detection signal responder configured to respond that the position detection signal is detected to the power supply managing device when the position detection signal is detected by the position detection signal detector.

摘要： A wireless communication apparatus for receiving a packet formed of a signal modulated by OFDM includes the following elements. A band-pass filter extracts an OFDM signal of a desired band. A low-noise amplifier having a gain controlled according to a received-signal intensity amplifies the desired OFDM signal. A frequency converter down-converts the amplified OFDM signal into a baseband signal. An analog-digital converter converts the baseband signal into a digital signal. A first high-pass filter removes a DC offset from the baseband signal corresponding to a predetermined preamble portion of the packet. A frequency-offset estimator estimates a frequency offset from the sample signals constituting the baseband signal from which the DC offset has been removed by the first high-pass filter. A frequency-offset corrector removes the estimated frequency offset from the baseband signal. A demodulator demodulates subcarrier signals arranged in a frequency domain from the baseband signal compensated for the frequency offset.
