    • Elektrisches Tiefpassfilter mit Sperrverhalten für eine vorbestimmte Sperrfrequenz, aufweisend eine Reihenschaltung mit einem FIR-Filter und einem IIR-Filter, wobei die Parameter des FIR-Filters im Wesentlichen auf das Sperrverhalten bei der Sperrfrequenz und die Parameter des IIR-Filters im Wesentlichen auf das Tiefpassverhalten abgestimmt sind. Mit einem derartigen Filter läßt sich mit relativ geringem Schaltungsaufwand und mit hoher Stabilität gegenüber Schwingneigung ein gutes Tiefpassverhalten mit sehr starker Dämpfung der zu sperrenden Frequenz erreichen. Ein solches Filter eignet sich beispielsweise als Schleifenfilter einer PLL-Schaltung.
    • 用封闭行为在预定的截止频率,它包括一个串联电路包括一个FIR滤波器和IIR滤波器,其中,所述FIR滤波器基本上在在截止频率处的锁定行为的IIR的参数和参数基本上滤除低通行为的电气的低通滤波器 匹配。 通过这样的过滤器是具有非常强阻尼良好的低通响应于被禁止频率可以用相对简单的电路和用针对振荡倾向高稳定性来实现。 这样的过滤器是适合于例如作为PLL电路的环路滤波器。

    • Word sense ambiguity, for "thematic" words in a sentence, is achieved based on thematic prediction. The senses of "thematic" words are disambiguated in a sentence by determining and weighting possible themes for that sentence. Possible themes are determined for that sentence based on thematic information associated with the different senses of each word in the sentence. A highly deterministic thematic-based word sense disambiguation method is used to preprocess the sentence prior to further syntactic and semantic analysis, thereby enhancing accuracy and decreasing the demand for computational resources (memory and CPU) by reducing input ambiguities.

    • An on-chip test circuit in an integrated circuit memory device includes a test mode terminal and a test data storage circuit having an input coupled to a data terminal of the memory device and an output coupled to a memory-cell array in the memory device. The storage circuit further includes terminals adapted to receive respective read test data and write test data signals. The storage circuit stores bits of data applied on the data terminal when the write test data signal is active. The storage circuit provides on its output the bits of stored data when the read test data signal is active. An error detection circuit includes a first input coupled to the memory-cell array and a second input coupled to the output of the storage circuit. The error detection circuit develops an active error signal on an output when the data on its input is unequal. A test control circuit is coupled to the terminals of the test data storage circuit, and to the test mode terminal. When the test mode signal is active, the test control circuit operates in a first mode to transfer data on the data terminal into the storage circuit, and operates in a second mode to transfer data from the storage circuit to the memory cells in the array. The test control circuit then operates in a third mode to access data stored in the memory cells and in the storage circuit such that the error detection circuit compares the data stored in each addressed memory cell to the data initially transferred to that memory cell.
