摘要： In a method for avoiding transients during switching processes in integrated circuits, a module of the integrated circuit is switched from a first operating state to a second operating state, a load change occurring thereby. In this case, it is ensured that the occurring quotient of load change and time duration for the transition from the first operating state to the second operating state does not exceed a predetermined limit value, thereby reducing or avoiding transients associated with such switching.

摘要： The present invention relates to a receiving apparatus for a mobile communications system which can be modulated using different modulation types at the transmitter end. According to one embodiment of the invention, in the middle of a data burst of a Bluetooth communications system, a GFSK modulation method is switched to an M-DPSK modulation method, which is used for the payload data. A frequency offset estimation unit is provided for GFSK-modulated signals in a first receiving section and estimates the frequency offset by averaging over a bit sequence of a trailer of a data burst. The frequency offset is corrected in a second receiving section, by means of a frequency correction unit which operates on the basis of the CORDIC algorithm.

摘要： A receiver circuit of a cordless communication system has an analog signal processing section with a channel selection filter and a digital signal processing section which is connected downstream of the latter and has a group delay equalizer. The group delay equalizer is used to equalize the digital distortion caused by the channel selection filter.

摘要： The present invention relates generally to a converter circuit with a limiter to convert an analog reception signal into a value-discrete limiter signal. An evaluation circuit determines a zero crossing distance signal from the temporal distances between successive zero crossings of the limiter signal. A synthesis circuit calculates a digital processing signal whose zero crossings correspond to those of the limiter signal and whose pulse shape has a smaller spectral width than a rectangular pulse.

摘要： In a method for estimating a sequence of input data symbols of a CPFSK-modulated data signal transmitted via a faulty channel, in the course of an ACS operation for calculating a transition metric value, an estimated value is determined for the replacement symbol occurring during the linear approximation of the CPFSK. That estimated value is considered in calculating the transition metric value.

摘要： The invention relates to a demodulator and also a demodulation method and enables a reliable demodulation even when the intermediate frequency range overlaps the range of the data frequencies of the signal. For this purpose, a rapidly oscillating output signal is generated from the in-phase signal and also the quadrature signal, the sign of which output signal varies in a manner dependent on the product of the signs of the in-phase signal and of the quadrature signal. Either an XOR gate or a multiplier stage may be used in order to generate an output signal of this type.

摘要： An integrated circuit has a clock subsystem, and a circuit. The clock subsystem is configured to provide a reference clock signal to a first module and a second module. The circuit is configured to distribute information describing characteristics of the reference clock signal to the second module. The information distributed with the circuit enables the second module to adapt the reference clock signal based on the information.
