    摘要： A phase differential calculator comprises: a first phase accumulator configured to generate information indicative of the phase of a local sample clock at a first resolution; a clock generator configured to generate a generated clock and information indicative of the phase of the generated clock at a second resolution that is lower than the first resolution as a function of a phase comparison and in synchronism with a remote sample clock; and a phase comparator configured to generate the phase comparison based on a phase difference between the information indicative of the phase of the local sample clock and the information indicative of the phase of the generated clock.

    摘要： The invention relates to an isolation material (1), which is applied on the structures and surfaces where it is desired to provide isolation, in order to prevent the possible deformation by protecting said structures and surfaces against external factors, said isolation material being produced to extend the lifetime of the isolation by using the liquid, moisture and vapor impermeability feature of the plastic-derived material constituting the intermediate layer (2), and to obtain the possibility of rapid, easy and economic application and use for the bitumen (asphalt) (4) coated using the fibrous material (3). Said isolation material (1) is not easy to burn, is not affected by the temperature differences and is not influenced for a very long time by the factors such as sun, rain, snow, naturally occurring chemicals, plant roots, direct contact with the soil and time; hence it enables the isolation to last for long years.

    摘要： Die Erfindung betrifft ein Verfahren und eine Schahungsanordnung zur Anpassung von zwei Systemen zur Übertragung oder Verarbeitung von zeitdiskreten Signalen mit unterschiedlichen Abtastraten und ist dadurch gekennzeichnet, daß das Quellensignal auf L Pfade zyklisch mit der Abtastrate des Quellensystems verteilt wird, daß das verteilte Signal nochmais auf M parallel geschaltete Filterzweige geteilt, dort gefiltert und gehalten wird und daß die M Filterzweigausgänge der L Pfade jeweils zyklisch mit der Abtastrate des Senkensystems abgetastet und die Abtastsignale aufsummiert werden. In vorteilhafter Weise ist in allen Filterzweigen keine höher Verarbeitungsrate fi/L = fo/M wirksam.

    摘要： A discrete state-space filter directly applies a linear transfer function that describes the frequency-domain representation of an IIR filter or control plant to asynchronously sampled data. The discrete state-space technique maps a continuous time transfer function into the discrete state-space filter and stores the states of the filter in a sample-time independent fashion in a discrete state-space vector. The filter states are propagated with the asynchronous time measurements provided with the input data to generate the filtered output.
