摘要： A low noise analog filter with adjustable filter frequency includes an oscillatory circuit, whose resonance frequency equals the filter frequency of the filter. The oscillatory circuit has a first circuit branch. One of the frequency determining elements is a capacitance and the other an inductance. The low noise analog filter further includes an amplifier with adjustable amplification installed in one of the two circuit branches. The output of the amplifier is connected with its inverting input via the frequency determining element arranged in such circuit branch. In filter operation, the amplifier amplifies, according to the adjusted amplification, a voltage applied across the frequency determining element arranged in such circuit branch and thereby effects a corresponding change of an electrical current flowing through such frequency determining element.

摘要： An optical sensor device for detecting reflecting objects (11) has a light pulse emitter (12) and a light receiver (13) connected to an evaluation circuit (14) having a pulse generator (17) and a reception signal processing stage (24) which only emits an object detection signal when the light pulses or light pulse sequences received by the light receiver (13) lie above a switching threshold. The evaluation circuit (14) has a pulse emission influencing and triggering stage (15) connected in parallel to the reception signal processing stage (24) which triggers the emission of the following light pulse by the pulse generator (17) only when a detected variable disturbing signal has disappeared.
