Abstract: The occurrence of a ground fault can be detected more accurately. A ground fault detection device is for detecting a ground fault in a conductive path for supply of power from a first power source to a second load in an in-vehicle system. The ground fault detection device includes a voltage detection unit that detects a voltage value of the conductive path, a current detection unit that detects a current value of the conductive path, and a control unit that determines whether or not a ground fault occurred in the conductive path, based on an evaluation value that increases as the voltage value detected by the voltage detection unit decreases, and based on the current value detected by the current detection unit.

Abstract: A protector apparatus is used in a power supply system for supplying power to loads and includes a power path and a relay. The power path includes a first conductive path, which is connected to a first power supply unit, and a second conductive path, which is connected to a second power supply unit. A relay switches the first conductive path and the second conductive path between a permitted state and a cutoff state. The first conductive path is provided with first connecting portions in a protected region from the relay toward the first power supply unit. The first connecting portions of the first conductive path are entirely covered by a protector, and in the protected region, the protector insulates the first conductive path from the periphery of the protector. The second conductive path is connected to the load, which is a load to be protected, out of the loads.

Abstract: A digital baseband signal for radio frequency transmission is processed prior to performing digital-to-analog conversion. The digital baseband signal is filtered. The number of bits of the digital baseband signal is reduced to minimise the size of the digital-to-analog converter. By performing some of the bit reduction before filtering, the size of the filter circuit is reduced whilst still meeting relevant performance parameters.

An amplification gain controller outputs a gain control signal to an automatic gain control amplifier to amplify the received signal with maximum value when receiving a burst detection trigger signal.

A received digital signal is amplified with the second gain and integrated to find the reception signal power, from which a third gain control signal is calculated and outputted to the automatic gain control amplifier to amplify the received signal with this third gain.
