Abstract: The phase shifter oscillator with a voltage-controlled output frequency uses a series of basic circuits (GS1, GS2, GS3...) with 2 symmetrical inputs , a control input (S1), a reference input (S2) and a symmetrical output . The inverting and non-inverting inputs of each basic circuit (GS1, GS2, GS3) are each coupled to a pair of outputs  of another basic circuit. The first control inputs (S1) of all the basic circuits (GS1, GS2, GS3...) are connected in common and supplied with a tuning potential (Ua), their second reference inputs (S2) supplied with respective reference potentials (Ur1, Ur2..). At least one output  of at least one basic circuit (GS1, GS2, GS3..) is used as the signal output of the phase shifter-oscillator.

Abstract: While wave digital filters (WDFs) can always be implemented by commercially available integrated digital signal processors (DSPs), the efficiency of such implementations leaves room for improvement. Modified forms of WDFs are therefore derived that yield DSP implementations much more efficient than those previously available. The approach is particularly suitable for lattice WDFs. The modified WDF-structures can be easily built in such a way that they possess all stability properties desired under signal quantization, thus not only absence of small- and large-scale limit cycles but even e.g. forced-response stability and related properties.

Abstract: A process to determine malfunctioning detectors in a danger signaling system having a control center and at least two-wire signaling line joined to multiplicity of detectors. Control center emits voltage-modulated digital control and interrogation data to the detectors, and the detectors when interrogated by the control center emit current-modulated digital data to the control center; if faulty data are received following an interrogation, control center emits a voltage signal to the detectors for closing the switches of all detectors; the power input of the detectors is measured and saved in a measured-value memory; the control center subsequently provides an impressed current of a preset magnitude to the line; an evaluation device opens the switch if the power input does not exceed a preset measured value and the voltage dropping on a measuring resistor reaches a preset value; the detector next in succession also opens the switch if the voltage dropping on its measuring resistor reaches its preset value and the power input does not exceed the preset maximum to identify the malfunctioning detector.
