Therefore, the error voltage is returned for automatic correction.

This signal represents the misalignment voltage caused by the drop in resistance-voltage in the Hall element.

In the case of incorrect compensation there is a fault voltage at this second point G.

Elements such as distortion, error voltage, and noise are included.

This procedure is repeated until the fault current and the fault voltage are in phase.

Another possibility of reducing the error voltage consists in that, according to FIG.

Upon incorrect focussing of the two-axis element, an error voltage will result which is applied to the focus servo 16.

For the presently described travelling wave fault location, the fault voltage at the initially unknown fault location F is considered.

There also can serve a different fault voltage Sf than that delivered by the radar as a measure for the target eccentricity.

The error voltage E from the output of differential amplifier 84 is coupled to the (+) inputs of error comparators 98 and 100 via identical resistors R19 and R20.

On the primary side, the summation transformer 4 has four primary current branches P1, P2, P3, P4 surrounded by a secondary winding 5 which supplies a fault voltage for triggering a switching relay 6 when a fault current occurs. The switching relay 6 in turn mechanically actuates the switching lock S of the switch 3 for opening all switching contacts S1, S2, S3, S4.

For example, the error voltage E will not change the status of level comparators 98 or 100 until the spout 14 and the tongue 16 are misaligned by at least 18°.

For example, either level comparator 98 or 100 changes state to correct the spout position in response to an error voltage E which represents a spout-tongue misalignment or MA(max) of only 3°.

However, in this case there is no proportionality between the d.c. current and the optical output of the light signal in the individual detector means, and the sign of the error voltage would be lost.

As long as the frequencies of the input signal and of the comparison signal are far apart, the difference frequency falls outside the passband of the low-pass filter and an error voltage is not produced at the input of the oscillator (VCO) of the phase-locked loop.

The error voltage U ERR dropped across the elements 2019 and DL? due to the flow of current is detected by a further amplifier 2023, which is wired up to form a measurement amplifier 1991 EL, and the corresponding analog output voltage U Diff is fed to an A/D input of a microcontroller 21 (not illustrated here in the figures).

Given an appropriate magnitude of the terminal voltage of the source Q SG, the error voltage in the case of the receiver subjected to reception interference can thus be compensated for, at least partly or completely, across the entire bus termination (i.e., terminating load of all the remaining subscribers and, if appropriate, an additional error load).

But since offset voltage UF at terminal 190 will be limited to the dividing factor, it must be again increased according to the dividing factor in sample and hold stage 160 so that the compensating voltage UK has the necessary amplitude after the correction interval.

The simplest method involves measuring the signal at the Hall voltage connections for two opposing directions of the magnetic field, the misalignment voltage then being able to be eliminated by subtraction of the signals obtained.

It is to be noted that the misalignment voltage practically disappears when I1,2 =-IA,B =0.1 mA.

This misalignment voltage practically disappears of I1,2 =-IA,B =0.1 mA as in graph b).

Since in this embodiment, compensating voltage UK is subtracted directly from error voltage UF, two cycles of the test signal are required for the correction interval, since the new measurement values must be taken care of in sample and hold stages 12 and 13 following an overload of the threshold value.

In an advantageous manner it is provided that by means of the impedance converter (NF) the protective ring electrode (R1) continuously tracks the measuring voltage (UM) present at the measuring capacitor (MC1) exactly, except for an error voltage of maximally 1 ?V.

Accordingly, no voltage drop can occur in the region of the Hall voltage connections and thus also no resistance-induced misalignment (offset) voltage.

The measurements also show that a stray voltage occuring at a point D due to a potential transfer from the earth circuit at another point D1 could be higher or lower than UD1-VD, depending on the position of the transferring line with respect to the defective cable and to the conductors with external sheathing.

If the electrode distance increases, the error voltage UF increases comparatively more slowly than in the case of a corresponding reduction in that distance.

The speed error determined in comparison circuit 25 is then fed as an error voltage via the motor driver circuit of stage 14 to direct current motor 1.

A detected speed error or speed control signal is then fed as error voltage via the motor driver stage 14 to the direct current motor so as to correct the rpm of direct current motor 1.

In practical use, only one of these two resistors is required in general for compensating an error voltage arising at the inputs due to differring source resistances.
