    Abstract: A signal transmission apparatus includes a higher-level station, a lower-level station and a digital transmission device connected between the stations and having a signal transit time to be measured. Each of the stations has a transmitter for sending useful signals, each clocked by a respective clock signal, through the transmission device to other station. Each of the stations has a receiver for receiving the useful signals clocked by the other station and for separating out the clock signal superimposed on the applicable useful signal. The useful signal to be transmitted in the higher-level station is clocked by a given clock signal. The useful signal to be transmitted in the lower-level station is clocked by a clock signal derived from the clock signal separated out from the receiver of the lower-level station. The higher-level station has a phase comparator for comparing the given clock signal with the clock signal separated out by the receiver of the higher-level station and supplying a comparison outcome. The higher-level station has an arithmetic unit for calculating the signal transit time from the comparison outcome.

    Abstract: A switched capacitor network includes a switch device alternatingly charging two first capacitors having the same capacitance from a signal voltage source with polarities being opposite relative to a ground potential and then discharging each of the two first capacitors through the input circuit of a respective differential amplifier. The switch device alternatingly charges two second capacitors having the same capacitance in phase opposition with one another from a reference voltage source with the same polarities relative to the ground potential and then discharges each of the two second capacitors through the input circuit of a respective one of the differential amplifiers, in synchronism with the charging and discharging of the two first capacitors. The switch device charges each of two third capacitors having the same capacitance as the second capacitors in phase opposition with a respective corresponding one of the second capacitors from the reference voltage source with the same polarities relative to the ground potential and then discharges each of the two third capacitors through the input circuit of a respective one of the differential amplifiers.

    Abstract: An image sensor has an optical configuration for imaging an image to be recorded onto sensor elements. The sensor elements have dimensions below a resolution of the optical configuration. Neighboring sensor elements are in each case combined into pixel sensor regions. During the recording of the image, the measured values X of the sensor elements of each sensor region are averaged. In this case, each average value corresponds to a pixel of the recorded image. In this manner, production-dictated tolerances of the sensor elements are compensated for by the averaging.
