Abstract
The transmitter is alternately supplied via one of two pairs of opposite electrodes. The output signal is taken from the other pair of electrodes. According to the mean value of the absolute levels of at least two successive output signals, the true value of the HAll voltage is assessed. The transmitter is supplied via each pair of opposite electrodes the same amount of currents but of different frequency. The output signals are taken from the same pair of electrodes. They are selected according to the frequency and rectified.
