摘要： A circuit for operating loudspeakers includes a first, second, third and fourth loudspeaker circuit, having one input each for injecting a signal and one output each for connecting a loudspeaker input. The loudspeaker circuits are designed to amplify the injected signal and to provide the amplified signal at the outputs thereof. The loudspeaker circuits can, for example, be used for a 2.1 sound system. The three channels for a 2.1 sound system can be implemented by an amplifier circuit with four loudspeaker circuits, one loudspeaker circuit each being required for the two stereo channels left and right. A subwoofer channel can be driven differentially by two loudspeaker circuits. The stereo channels are, by contrast, only still connected to one loudspeaker circuit each, and so the stereo channels require at least one further common ground cable.

摘要： A method for synchronizing a clock signal with a reference signal is disclosed. One embodiment has a first synchronization part which has a bit pattern having a particular clock period, a pause whose length is a multiple of this clock period plus a fraction of the clock period, and a second synchronization part having the particular clock period. The method includes generating a phase difference signal which is proportional to a phase difference between the clock signal and the reference signal, filtering the phase difference signal and providing a filtered phase difference signal, driving a digital oscillator in such a manner that the frequency of the clock signal is changed on the basis of the filtered phase difference signal, the phase of the clock signal within a clock period being corrected by a value corresponding to the fraction of the clock period at an end of the pause in the reference signaled

摘要： A device for the production of standard compliant signals, for example pulse-type signals in a telecommunication network, serves the production and adaptation and/or pre-distortion of signals with a certain signal form, which is defined dependent on a standard signal form specified in a standard. The device comprises signal generation means (10) for the production of the signals with a certain signal form and signal adjustment means (20) for the adaptation or pre-distortion of the signals. The signal generation means (10) according to the invention are digitally realized, by using a programmable shift register (14), which contains multipliers specified by the standard signal form for multiplication with a digital input signal (1).

摘要： A blade arrangement of a gas turbine, with at least one blade which in the radial direction projects into a hot gas passage arranged concentrically to an axis, and terminates in a blade tip which with a clearance lies opposite a heat shield which delimits the hot gas passage. The blade and the heat shield are movable in relation to each other in the circumferential direction, and the blade tip and the heat shield are covered with coatings, which enable a directed cutting of the blade tip into the heat shield. By such a blade arrangement, a reduction of the clearance as a result of cutting in is simply achieved by the heat shield having a porous thermal barrier coating as an outer, abradable coating, and by the blade tip being provided with a homogenous, metallic cover coating.

摘要： A method for applying a heat insulation layer (11, 12, 13) or a metallic protective layer to a thermally stressed component (200) having a basic material (10) in order to eliminate local damage (14) or an untreated place in the coating, includes, in a first step, pretreating the local damage (14) or untreated place, and, in a second step, applying layers (17, 18) necessary for eliminating the local damage (14) or untreated place. A markedly improved lifetime of the processed component can be achieved in that, within the first step, the edge regions (15) of the layers (11, 12, 13) ending at the local damage (14) or untreated place are processed so that they form uniformly sloped and terrace-shaped edge regions (16). Furthermore, a precharacterization of the entire coated region of the operationally stressed component or critical places by FSECT makes it possible to reduce the risk in terms of otherwise overlooked layer regions, the remaining lifetime of which would not persist for the following operating time.

摘要： The invention provides a method for recovering a digital datastream, in which a reference clock phase is recovered from the digital datastream, the digital datastream being received in a datastream receiver, low-pass filtered in a low-pass filter device, an edge position signal being determined by comparing an amplitude of the low-pass filtered datastream with a predetermined threshold value in an edge position detection device and a phase deviation being determined from a time difference between a 0/1 threshold intersection point of the threshold value with a 0/1 data transition or a −1/1 threshold intersection point of the threshold value with a −1/1 data transmission and the target time of the control system in a phase correction device, so that the phase deviation can be corrected with the phase correction offset in the phase correction device.
