摘要： The invention is directed to a receiver arrangement, for example, in a mobile radio, which allows the use of slowly locking phase locked loops for a point-to-point connection between two transceivers, even in the case of a heterodyne receiver structure. The need to change channels between a transmission slot and a reception slot is avoided by virtue of a changeover device being provided for the purpose of interchanging the in-phase and quadrature components at the input side on a down-conversion frequency mixer. This advantageously allows either the upper sideband or the lower sideband of a useful signal to be down-converted without the need to change channel.

摘要： When data bursts are transmitted between a base station and a mobile receiver, a changeover is made between a plurality of modulation methods during an existing radio link for modulation of the data. For resynchronization of the receiver in the event of the changeover, synchronization information items are determined from a first part (ET) of the data burst modulated by a first modulation method, and are used for synchronization with a second part (ZT) of the data burst modulated by the second modulation method.

摘要： A PLL circuit (1) is regulated by means of a digital modulation signal (28) at a first frequency, and is then regulated at a second frequency, by deactivation of the digital modulation signal (28). A difference signal (32), which is characteristic of the voltage change in a control signal (22) for the VCO (7) which is produced by deactivation of the digital modulation signal (28) is compared with an analog modulation signal (34). The analog modulation signal (34) is changed so as to correct any discrepancy determined during the comparison.

摘要： 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.

摘要： A distance-measuring optoelectronic sensor for the monitoring of a working zone is provided which is located within a detection zone of the sensor and at a first distance from the sensor, wherein the sensor has a lighting unit having a light source to illuminate the working zone at least partly as well as an object detection unit by means of which unauthorized objects in the working zone can be detected. In this respect, an illumination control is designed, in a switching-on phase, first to activate the lighting unit with a lower power so that a provisional working zone at a second distance from the sensor less than the first distance is illuminated with at most a preset maximum power; to check by means of the object detection unit whether an unauthorized object intrusion is taking place into the provisional working zone; and if no unauthorized object intrusion is recognized, to activate the lighting unit at a higher power so that the working zone is illuminated with at most the preset maximum power.

摘要： The present invention is directed to a receiver for a wire-free communication system for reception of a received signal which is modulated using a digital modulation method having a first frequency conversion device for production of a frequency-converted received signal by conversion of the received signal to an intermediate frequency. The receiver further includes a pre-filter for production of a filtered received signal from the frequency-converted received signal such that the received signal is band-limited, and an analogue/digital converter for production of a binary received signal from the filtered received signal by comparison of the filtered received signal with a level threshold. In addition, the receiver includes a phase reconstruction device for production of a phase-reconstructed received signal by reproduction of the phase of the received signal from the time intervals between zero crossings of the binary received signal, and a mapping device for production of a bit sequence by mapping symbols from the phase-reconstructed received signal onto this bit sequence using the digital modulation method.

摘要： The present invention provides a two-point modulator arrangement with a PLL that can be operated at various reference frequencies. A modulation signal provided by a digital signal processor is supplied as an analog signal at the input of the oscillator in the PLL and as a digital modulation signal on a frequency divider. For the purpose of pulse shaping the digital modulation data, a digital filter is provided that is coupled to the control input of the frequency divider and, in line with the principle proposed, is operated at the same, constant clock frequency as the signal processor, regardless of the reference frequency. As a result, no resynchronization of the digital modulation data is necessary upstream of the digital filter.
