A method for dynamic noise reduction of magnetic field sensor signals of a magnetic field sensor circuit with a magnetic field sensor and a switching device, wherein the magnetic field sensor provides a sensor signal to a sensor output, and wherein the switching device comprises a signal comparator, a low pass filter and a multiplexer, and wherein the switching device comprises a signal input interconnected with the sensor signal output and a signal output, and wherein the signal comparator has a first input interconnected with the signal input and a second input interconnected with the low pass filter, and a control signal output interconnected with the multiplexer. In a first method step, the sensor signal is compared to the level of a signal of the low pass filter by means of the signal comparator, and the result is compared to a predetermined threshold value.

Method for dynamic noise reduction of magnetic field sensor signals and a magnetic field sensor circuit with dynamic noise reduction

The invention relates to a multistandard receiver circuit for analogue and digital broadcasting, particularly analogue and digital television broadcasting, having a demodulator arrangement with an input for applying digital or digitized values (d) for both analogue and digital broadcasting signals from a tuner () and with components and/or an algorithm for processing the values (d). Emphasis should be given to an embodiment and/or controller for processing the values (d) for all processing steps which are to be performed in the field of intermediate-frequency processing with shared components.

Multistandard receiver circuit for analogue and digital broadcasting

The invention relates to a method and a circuit arrangement for deciding a symbol upon the reception of a signal including or coupled with a quadrature signal pair, wherein the decision is made by means of an analysis of the metric of at least one reception point to at least one nominal point in a complex coordinate space, and the metric is analyzed in the non-Cartesian or not exclusively Cartesian complex coordinate space. The decision is made after the analysis, and during the decision process, a second most probable nominal point and a reliability of the decision are determined.

The invention relates to an apparatus and method for processing received data (I/Q, I/Q; d, d) of a radio interface, wherein the received data includes a sequence of data which have been transmitted for the purpose of error reduction through different branches of a carrier (R) of the radio interface, and which are combined into a sequence of data (DATAOUT) to be outputted, wherein the combining is implemented on the basis of carrier information values (R, SINR) of the different branches (k) relative to each other. A maximum ratio combining (MRC) is implemented in which the amplitudes of the branches of the carrier information (R, (R) are combined using a division method as a function of a disturbance information value (MIX, SINR, SINR) of the branches (k).

Method and device for processing received data of a radio interface

A bit sequence (b, b') from QPSK or QAM symbols is decoded, in which an associated receive probability (w, w&#x2032;) is assigned to each receive bit (b, b&#x2032;). The receive probability (w, w&#x2032;) is adaptively determined taking into account the transfer properties of the channel.

Bus system (1, 2, 3) for a television signal processing device for transferring video data (d8) of at least one video data source (8) and/or supplementary data (d10) of one or more supplementary-data sources (10) between a transmitter (1) and a receiver (3) by means of a bus (2), wherein at the transmitter end (1), a single data stream (d2) for the bus (2) is formed from the video (d8) and/or supplementary data (d10) by means of an interface circuit (4). The interface circuit (4) combines the video and/or supplementary data, source by source, into blocks (db; db1, db2) following each other successively in time and containing identification data (dk; sk, ik) for start and end, or start and length, and content identification, and transfers the blocks serially.
