    摘要: A digital control circuit with a device for generating a high-resolution tuning voltage is suitable for use in receivers for RF signals, particularly in consumer equipment. The tuning voltage can be electronically switched from one value to another at a high speed. The transient time required with conventional control loops is nearly eliminated since the low-pass filter or the digital integrator is preset to its steady-state integration value. To generate the tuning voltage, dynamic digital-to-analog convertors are provided which, despite their high resolution, require only a smoothing filter with a short response time and a short time constant.

    摘要: A processing device embodied in an integrated circuit may be divided into first and second functional units. A mount for the integrated circuit may be assigned to the first functional unit, which may define the external electrical connections of the processing device. Processing may take place in a second functional unit of the processing device, whose essential connections may normally be accessible from outside via the external connections of the first functional unit. The processor device having first and second functional units in a mount may be similar to a hybrid circuit but may serve a different purpose. The first functional unit, which may also comprise more than one monolithic integrated circuit, may define the external connections and may make available suitable matching circuits for the second functional unit. In this manner, the processing device, which may be contained in the second functional unit and may also comprise more than one monolithic integrated circuit, may be considered to be “masked” as viewed from outside. In addition to the matching circuits, the first functional unit may contain subcircuits performing more general functions, such as oscillators, supply voltage regulator circuits, buffer circuits, protective circuits, etc.

    摘要: A signal separator, particularly a teletext-signal separator, includes an integrating unit which delivers a center-of-bit-indicating (i.e., center-crossing) signal and a residual-value signal. A residual-value-signal-evaluating device evaluates the respective residual value and uses a selection control signal to determine how the value of the current signal bit is to be estimated. This is accomplished by using a selection facility which derives from the current sample value and the preceding and subsequent sample values the respective preaverage value and postaverage value and selects the value best suited for the estimation using the selection control signal. A phase corrector evaluates a signal pattern from an edge logic which indicates whether the current sample value is approaching an edge of the signal, and controls a change of the integration period if the residual-value signal lies within a predetermined residual value signal range.

    摘要: A system for exchanging data includes at least two memory units, each unit functioning as both a transmitter and a receiver of data. The exchange of data occurs whenever at least two memory units are within a certain distance of each other. The user is thus capable of simultaneously being both a transmitter and a receiver of data, such that the transmitter can send data continuously but can receive data transmitted from other memory units only when the receiver is within a certain distance from a transmitter. As a result, data are received only by those memory units that are located in the immediate environment of the transmitter. Since the data transmitted can be selected personally by the user, the data thus reflects the preferences of the user acting as the transmitter.
