Abstract: An apparatus includes a sensor excited by an input voltage adapted to provide a sensor output first voltage corresponding to a physical input excitation. A transformation circuit device provides the operational voltage to the sensor, detects the sensor output first voltage, nulls an amount of offset voltage in the sensor output first voltage, amplifies the nulled offset sensor output first voltage, and provide a noise filtered and temperature compensated output second voltage. A simulator circuit receives the compensated output second voltage and provides an output third voltage representative of a simulated bridge sensor, being absent of offset voltage, and being independent of temperature dependence and noise in the sensor.

Abstract: A multi-pole variable reluctance resolver is balanced wired and driven by 180 degree differential signals. Capacitive passive elements may be serially added to the resolver to minimize magnetic interference and cancel flux between poles of the same polarity and orthogonal poles, as well as minimize the effect of input driving signal distortion. Symmetric networks of resistive and capacitive elements may also be added to the resolver to overcome noise sensitivity associated with balanced wired resolvers.

Abstract: A method for accurately acquiring multiple analog input signals that are converted using a plurality of A/D converters into corresponding digital single measured values. A first measurement averaging cycle having a predetermined total number of measuring intervals is predetermined by a higher-order control unit. First and second input signals are acquired by first and second A/D converters in a first and second number of measuring intervals, the second number being smaller than the first number. The first and second input signals are averaged to form first and second measured values, respectively. The first input signal is acquired by the second A/D converter in a third number of measuring intervals as at least one further single measured value. A message is output if a deviation of the at least one further single measured value from a single measured value of the first input signals measured by the first A/D converter or from the first measured values averaged up to that point exceeds a maximum permissible absolute value of the deviation.

Abstract: A method for digital triggering of a digital recording of a digitized measurement signal having a superimposed noise signal. The method includes generating from the digitized measurement signal a digital triggering signal for the digital triggering of the digital recording of the measurement signal, and performing band-limitation of the noise signal superimposed on the digitized measurement signal via a low-pass filtering before the digital triggering signal is generated. The bandwidth of the low-pass filtering is adjusted dependent upon edge steepness of the measurement signal, in order to reduce variance σt2 in jitter of the digital triggering signal.
