Abstract: The invention relates to a method for extracting measuring signals from a multi-channel photomultiplier, characterised by the following steps: a measuring signal which is integral for the channels of the photomultiplier is extracted at the dynode in order to record the signal form and intensity of an event, and the anode signal of each channel is compared with a threshold value. If the threshold value is exceeded at a channel, the location of the detected event is determined and the associated signal form and intensity at the dynode is detected. The invention also relates to a circuit for a multi-channel photomultiplier (1), said circuit being used to carry out the method according to one of the claims 1 to 8. The circuit comprises a photocathode, a multi-channel structure for electron multiplication (dynode), and anodes (11) which are associated with the channels and are used for pixel-oriented charge amplification and collection.

Abstract: A long-term integrator, e.g. for integrating the voltage signal from a coil measuring magnetic induction, can include a push-pull modulator followed by an analog-digital converter, a digital signal processor and a digital analog converter in cascade. Offset voltage in the analog-digital converter or an amplifier upstream thereof is nullified in the digital signal processor by modulating it as the measured signal is demodulated, thereby balancing out alternate polarity portions of the offset voltage.

Abstract: A temperature compensating circuit for a Hall generator with a positive temperature coefficient of the resistance of the drive circuit path utilizes summation of a voltage representing the drive current as detected across a substantially temperature-independent compensating resistance in the drive current path, with a constant voltage component to provide one output to an operational amplifier whose other output is connected to this operational amplifier which produces the output signal of the circuit.
