摘要:
The invention relates to an apparatus and a method for ascertaining and correcting the optimum sampling time for an oversampled input bit stream. This involves feeding the data bit blanked with the current sampling phase into the comparative sequence and using the data bit to ascertain a new, corrected sampling phase. This decision-based approach enables the sampling phase to be continuously corrected.

A hybrid satellite positioning receiver architecture is provided with a first receive path and a second receive path. The first receive path downconverts received satellite positioning signals of a first type to an intermediate frequency range, and the second receive path downconverts received satellite positioning signals of a second type to the same intermediate frequency range.
摘要:
In a method for qualification of the transmission quality of a frequency channel in a wire-free communication system that has two or more frequency channels, units in the system communicate via the frequency channels. Data is transmitted in time slots in a time pattern using a time slot method. The influence of possible interference sources is determined in a measurement time slot in which no data is received, in that the field strength is measured at the frequencies of two or more frequency channels, and the field strength information is used for qualification decisions relating to the frequency channels.

In a method for avoiding transients during switching processes in integrated circuits, a module (2.1, 2.2, 2.3) of the integrated circuit (1) is switched from a first operating state to a second operating state, a load change occurring. 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 limit value that is predetermined or can be predetermined in a targeted manner.

A frame structure for transmitting data over a digital interface has a plurality of data frames. In this plurality of data frames a first sampling data frame is based on at least one sampling word and dedicated to a first logical channel. A set of data frames follows the first sampling data frame and carries in a compressed format a plurality of predefined status data words dedicated at least to the first logical channel. A first further sampling data frame follows the set of data frames. It is based on at least one further sampling word and dedicated to the first logical channel.

摘要:
An integrated semiconductor component includes a functional circuit and a power control circuit configured to generate a supply voltage from an input voltage. The power control circuit may include a snitching controller and a control circuit configured to set a frequency spectrum of tile Supply voltage and coupled to the switching controller. The control circuit may be configured to determine a current operating state out of at least two possible operating states of the integrated semiconductor component and to set the frequency spectrum dependent from the current operating state.
