Abstract: The invention improves the control behavior of a control circuit for digital signals which is used in AGCs (automatic gain control), using a simple supplementary circuit. In a first example of an embodiment, the output signal of an integrator member is looped back to the input of said integrator member in the loop-back branch of the control circuit. In a second example, a counter is provided. Said counter monitors the overflow of the integrator member and weights the input signal accordingly.

Abstract: The invention relates to a plain bearing shell for supporting an engine crankshaft or camshaft, or as a connecting rod bearing shell of an engine, the plain bearing shell comprises a radially outward protruding holding projection in the region of the separating surface of the plain bearing shell. In order to simplify handling of the plain bearing shell during assembly, the bearing shell is formed in such a way that the holding projection merges continuously into one separating surface of the plain bearing shell, and is formed by a stamping tool from the outside of the plain bearing shell by an approach in which, in the region of the separating surface, the stamping tool compressively deforms the material on the outside of the plain bearing shell, essentially tangentially relative to the plain bearing shell and toward the separating surface, while a counter-holding mechanism is applied to the separating surface, to which mechanism the formed material of the holding projection extends.

Abstract: A network processor exchanges data of various descriptions via a plurality of network nodes with external network devices, such as other processors, controllers, transducers, or sensors. The network processor includes a master processor for control tasks of the processor, and a network coprocessor for supporting network tasks. A first and a second bus system, associated with the master processor and the network coprocessor with its associated functional units, particularly Data Link Layer memory devices, respectively, serves to separate the two fields of tasks from each other. This permits both a support of gateway functions and a support of Higher Layer functions. Higher Layer memory devices, whose messages are ultimately sent or received by the master processor, are accessible from the master processor or the network coprocessor directly or indirectly via the first and/or second bus systems.

Abstract: For the purpose of largely suppressing the noise pulses caused in a stereo radio receiver in the reception signal, particularly by the ignition system of a motor vehicle, a digital field strength signal representing the analog field strength signal is produced for example by digitizing the analog field strength signal. The scanning values of the digital audio signal, for example of the (L+R) signal, are produced by interpolation for at least as long as the digital field strength signal is outside a presettable tolerance range.

Abstract: Noise that is normally generated during the switching of a noise shaper may be reduced by switching the noise shaper to an inactive or off state after the occurrence of one or more predetermined criteria, for example the detection of a predetermined number of data values below a threshold value or equal to a certain value, or of a predetermined number of data values within a threshold region about a value that is constant with respect to the data values.

The reconstructed signal curve is utilized to determine the phase position of the sampling clock relative to the analog signal. This phase position is provided to a control loop which readjusts the phase position of the sampling clock accordingly.

Abstract: A system for converting analog video signals to digital video signals receives an analog video signal that generates a reference horizontal synchronization signal. A phase-locked loop receives the reference horizontal synchronization signal and generates a pixel clock signal and a horizontal synchronization signal from the reference horizontal synchronization signal. An analog-to-digital converter converts the analog video signals to digital video signals. Differences between the measured values of the sampling of a test line of adjacent pixels are formed and phase parameters of the different phase positions are generated by summation of these differences. A phase position of the video signal from the phase parameters is determined, and the phase position is determined with the set phase position, and based on the comparison the set phase is changed.
