Method for selective filtering |
September 12, 2006 |
| A method for digital clock recovery and selective filtering includes prescribing or calculating first coefficients of a prototype of a selective filter at a characteristic frequency fc for a given sampling frequency fa. Second coefficients of a selective filter are calculated at the |

Analogue frontend |
February 18, 2003 |
| An analogue frontend, such as is used, for example, in receivers for communications equipment, comprises a plurality of analogue components (1-3) which are connected upstream of an analogue/digital converter (4). In order to control the drive level of the individual analogue components |

Method for processing a signal containing data symbols |
September 24, 2002 |
| A method for processing signals composed of data symbols that are each separated from one another by a guard interval. Such signals are used for digital television transmission, for example. The guard intervals results in that gaps in the flow of recovered data are produced at the recept |

Nonrecursive digital filter and method for calculating the coefficients of the filter |
September 3, 2002 |
| The nonrecursive digital filter has variable coefficients for the purpose of shifting the frequency response from one characteristic frequency fc1 to another characteristic frequency fc2. The method enables calculating the coefficients of the nonrecursive digital filter for shifting the |

Circuit for demodulating two-dimensional data symbols transmitted by a carrier-based data transm |
July 23, 2002 |
| A circuit for demodulating two-dimensional data symbols transmitted by carrier-based data transmission. The circuit has a tuner and a quadrature demodulator. The tuner has a first intermediate frequency stage for converting a carrier frequency of an input signal containing the two-di |
