    摘要: A method of monitoring an analogue signal output from a sensor comprising comparing the amplitude of the analogue signal to a first threshold pair, wherein the first threshold pair comprises a first high threshold and a first low threshold, setting a primary monitoring signal to a first value when the amplitude of the analogue signal exceeds the first high threshold, setting the primary monitoring signal to a second value when the amplitude of the analogue signal decreases below the first low threshold, comparing the amplitude of the analogue signal to a second threshold pair, wherein the second threshold pair comprises a second high threshold and a second low threshold and wherein the second high threshold is greater than the first high threshold and the second low threshold is less than the first low threshold, setting a secondary monitoring signal to a first value when the amplitude of the analogue signal exceeds the second high threshold, setting the secondary monitoring signal to a second value when the amplitude of the analogue signal decreases below the second low threshold, comparing the primary and secondary monitoring signals and determining from the comparison whether an error exists with the monitoring of the analogue signal.

    摘要: The invention relates to a method and an arrangement for performing triggering and for determining a triggering moment. In the solution, a unipolar electrical pulse of a detector (106, 118) is converted between the detector (106, 118) and a first amplifier (108, 120) succeeding the detector into at least one bipolar electrical oscillation. The bipolar electrical oscillation is amplified with at least one amplifier (108, 120) and triggering is performed at a zero level between the extreme values of the bipolar electrical oscillation. In addition, a triggering moment is determined, at which the amplified bipolar electrical oscillation crosses the zero level between its extreme values.

    摘要: A differential threshold voltage level detection circuit (300) receives (310, 350) a differential voltage pair (VP, VM) as an input, applying each component of the differential pair to an individual voltage shifting circuit (315). Each voltage shifting circuit is configured with a regulated (318) current producing a shifted and a non-shifted version in-phase ( VPH, VPL, VMN, VML). For a shifted set of output differential voltages, the shift magnitude is proportional to the current entering a shifting circuit and is configured to be less than a peak-to-peak magnitude of the differential voltage to be detected. A current mirror within the detector contains a current reference (Iref) configured to produce a current to be passed through a voltage generator. The current magnitude is sufficient to generate a regulated voltage output to the two current regulating devices that supply the voltage shifting circuits. An overlap detector (500) receiving (540-546) both differential voltage pairs (330, 335, 370, 375) produces a signal (VOUT) indicating an input is at a detection threshold.

    摘要: The invention relates to a method for the filtering of noise from measured signals (sM), which are corrupted by pulsed noise signals (sST) with a known or determinable noise pulse separation (TSt), whereby the recording duration (?tE) for an individual measured value (E) is smaller than a noise pulse duration (Attest) and several individual measured values (E) are recorded with freely selected time separations (TE) in the measured signal (sM). A reliable avoidance of noise generated by noise sources transmitting in a pulsed manner is achieved, whereby at least three sequential individual measured values (E) are recorded with time separations (TE), different for the noise pulse separation (TSt) and a noise-filtered, measured parameter (M) is determined with the at least three individual measured values (E).

    摘要: Described is a device for transmitting signals between parts which are moving relative to each other, the device consisting of a signal source and a signal sink connected by a transmission channel. The invention is characterized in that located along the transmission-channel signal path is a symmetrical coupling device which transmits the symmetrical signal from the signal source between the moving parts. Alternatively, located in the transmission-channel signal path is at least one line which terminates, at least at one end, in a reflection-free resistor matching the characteristic impedance of the line and which feeds the receiver and/or, optionally, is fed by the transmitter. The device for the non-contact transmission of signals between moving parts includes, in the transmitter, a signal-conditioning circuit which increases the gradients of the edges of the signal supplied by the data source in such a way that the reciprocals of the rise and decay times are each greater than the lower limiting frequency for the transmission path. The receiver also includes a processing circuit which reconstructs the original signals from the pulses supplied by the transmission path wich are produced by differentiation of the signals produced by the transmitter.
