Abstract: A method for offset calibration of a rotation rate sensor signal of a rotation rate sensor. In a first step, an ascertainment is made that the rotation rate sensor is in an idle state. In a second step, after the first step, a filter parameter is determined as a function of the measured rotation rate sensor values, measured in the idle state, of the rotation rate sensor. In a third step, after the second step, a filtered measured rotation rate sensor value is determined with the aid of the filter parameter. An offset is determined with the aid of the filtered measured rotation rate sensor value.

Abstract: A peak amplitude detector for use in a synchronized position demodulator associated with a linear variable differential transformer. The peak amplitude detector adjusts for phase shift in the transformer and maintains the full bandwidth of the transformer. The detector obtains the maximum positive or negative amplitude of the sinusoidal signal at one of the secondary windings of the transformer by first counting either a positive or negative half cycle of the signal and then while down counting one half of the counted half cycle sampling the amplitude of the sinusoidal signal. The sampling ends when the count reaches zero.

Abstract: Processing waveform data for compressed display. A parameter to be displayed is measured, digitized, and displayed on a device that does not permit display of all of the data samples; thus, the digitized data is converted to a compressed form. For a compression factor of N input samples for each displayed sample, a displayed sample is taken from each successive group of N input samples. The choice of input sample is as follows: the sample having the maximum value of the group is chosen if all of the samples of the group are greater than or equal to the previous displayed sample; if all of the samples of the group are less than or equal to the previous displayed sample, then the sample having the minimum value is chosen; if the maximum and minimum values of a group straddle the value of the previous displayed sample, then a maximum sample and a minimum sample are chosen from the combination of that group and the next group. The technique can be applied in situations where N is not an integer. In such situations, the technique includes the calculation of an additional "pivot sample" for at least some of the groups.

Abstract: In a digital oscilloscope, the recording of transients exceeding a predetermined tolerance range is to be provided by simple means. A method and a device for carrying out this method are provided in which two envelope curves are stored in an envelope curve memory and these are then compared with cyclically repetitive amplitude samples of a signal curve. A trigger signal ensures that the signal curve containing the disturbance is served if one of the signal curves exceeds the tolerance range delimited by the envelope curves, which is the case, in particular, when interference signals occur. This curve can then be displayed for analysis on the screen. The invention can be applied within the context of digital measuring technology wherever signal curves are recorded and instantaneous disturbances must be detected.

Abstract: The invention is directed to a circuit arrangement for evaluating the signals of an inductive sensor such as the kind utilized on internal combustion engines. The coil of the inductive sensor is connected via a coupling capacitor to a differential amplifier connected in the form of a comparator. The coil of the sensor is also connected via the coupling capacitor to a resistance for equalizing charge as well as to a peak-value detector. The peak-value detector is connected to the input of the comparator either directly or via an amplifier circuit and effects a threshold adjustment for the comparator which occurs in dependence upon the signal supplied by the inductive sensor and in dependence upon the rotational speed. Manufacturing variations of the inductive sensor as well as temperature changes have no influence on the output signal.

Abstract: A method of obtaining the peak value of a signal. The signal is sampled at certain intervals of time. The value of the sampled signal is compared subsequent to sampling with a value previously stored in a memory. The higher of the two compared values is stored in the memory for later comparison with a value obtained during a subsequent sampling. The higher of the values stored in the memory is stored in another memory after a maximum signal has been obtained.
