    摘要: 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.

    摘要: Control circuit for arc welding components to workpieces, in which a component is placed on to a workpiece by a weld gun and after a welding stroke is lifted from the workpiece in a return stroke by igniting a pre-current arc and is brought up to the workpiece again in a forward stroke during the burning of an interconnected welding arc, in which a sequencing control determines the tripping moments of return stroke and forward stroke as well as of the welding arc and a monitoring voltage is bypassed from the pre-current arc ignited at the welding point, characterized in that the monitoring voltage (V) is converted into a correction voltage (line 27) by means of a set-point comparator (25) and is superposed on a control voltage (line 18) for principally controlling a high-frequency modulated switching mode power supply unit (15) and said switching mode power supply unit (15), in accordance with the thus corrected control voltage, adjusts its output current (lines 13,14) during the respective welding operation to the resistance value of the pre-current arc established by the monitoring voltage (V) representing the respective welding data.

    摘要: A tunable active high-pass filter particularly for use in hearing aids, which comprises merely a transistor as the active amplifying element. Three series-connected capacitors are connected between the input of the filter and the base of the transistor. A first resistor branches off from the junction between the first and second capacitors, a second resistor branches off from the junction between the second and third capacitors, and both resistors are connected, via a third resistor which is adjustable, to the emitter of the transistor which constitutes the output of the filter. A further resistor extends from the junction between the third capacitor and the transistor base to the source of operating potential which, for example, is positive. Preferably, each of the capacitors forms a high-pass filter with its respectively connected resistor with the first and second resistors, i.e. the resistors of the first and second high-pass filters, being located in the positive feedback path between the emitter of the transistor and its base. By the adjustment of only the value of the adjustable resistor, the steepness or slope of the filter can be varied within wide limits.
