Abstract: To transmit an anisochronic data stream on an isochronic transmission route with a plurality of channels over a transmission network, a number of channels is reserved by the transmitter before beginning the transmission, wherein the sum of the transmission capacities of the reserved channels just exceeds the bandwidth of the asynchronous data stream. During the course of transmission, the data of the anisochronic data stream are formed into packets; each packet is transmitted over the reserved channels. After a packet has been sent, unused portions of the reserved channels are filled with filler data that is discarded at the receiver, until sufficient data are again available at the transmitter to begin transmission of the next packet.

Abstract: According to a method for producing a solid body (1) including a microstructure (2), the surface of a substrate (3) is provided with a masking layer (6) that is impermeable to a substance to be applied. The substance is then incorporated into the substrate regions not covered by the masking layer (6). A heat treatment is used to diffuse the substance into a substrate region covered by the masking layer (6) such that a concentration gradient of the substance is created in the substrate region covered by the masking layer (6), proceeding from the edge of the masking layer (6) inward with increasing distance from the edge. The masking layer (6) is then removed to expose the substrate region under this layer, and a near-surface layer of the substrate (3) in the exposed substrate region is converted by a chemical conversion reaction into a coating (9) which has a layer thickness profile corresponding to the concentration gradient of the substance contained in this near-surface layer.

Abstract: A phase-locked loop locks relatively quickly to a pilot tone of the stereo-multiplex signal when a new transmitter is tuned in. The stereo-multiplex signal may be multiplied in a multiplier by the quadrature component of the pilot tone generated by a digital oscillator. The result is a control signal that is provided to a low-pass filter, and the low-pass filtered control signal is provided as a control signal to an oscillator which may include a table of length N and a counter for addressing the table entries. The zero phase angle ?0 may be set by a counter offset n0 by incrementing or decrementing the counter. A table may be utilized having a virtual length N+ which is larger than the length N of the real table. To access the real table, however, the corresponding MSBs of the actual count n(k) are used which match the address space of the real table of length N.

Abstract: A device for detecting and suppressing noise includes a noise detection device that receives and processes an input signal to determine if the input signal contains noise and provides a detected noise signal indicative of whether or not noise is detected in the input signal. A noise filter receives the input signal and when the detected noise signal does not indicate the presence of noise the noise filter provides an output signal equal to input signal. When the detected noise signal indicates the presence of noise the noise filter processes the input signal through a first filter to provide a filtered signal such that the output signal is equal to the filtered signal. The noise filter comprises a control circuit that receives the input signal and the filtered signal and in response dynamically adjusts a cut-off frequency control signal that controls a cut-off frequency of the first filter.

Abstract: To measure a physical parameter, a two-wire sensor produces pulse-width modulated signals (PWM) whose pulse width is preferably modulated as a function of the physical parameter to be measured. To indicate an error or a malfunction, the two-wire sensor provides an error signal with a specifiable pulse-width ratio that is preferably 1:1, while asymmetric pulse-width ratios are provided for the measurement signals (PWM). To measure a physical parameter that assumes only one of two states or values, the two-wire sensor produces a first measurement signal with a specifiable asymmetric pulse-width ratio and a second measurement signal formed by inversion of the first measurement signal. A plurality of two-wire sensors can for example be connected to a common two-wire line and operated in time-multiplex mode.
