    • A description is given of a circuit arrangement for producing a D.C. current, comprising a current-source stage, which is supplied on one input with a measuring current led via an input resistor, and which comprises a current source transistor whose base-emitter path is arranged in parallel with the input resistor and whose collector electrode forms an output of the current-source stage, on which output an output current is offered, a current mirror stage for mirror-inverting the output current of the current-source stage to a working impedance, on which working impedance a control voltage is produced in response to this output current, a current bank having a control input which is supplied with a control voltage, and having at least two outputs simultaneously controlled by the control voltage, on which outputs mutually proportional currents are offered of which a first current forms the measuring current. As a result, a current reference is created which can be used for very low supply voltages, preferably around 0.9 volt, is simple, shows a stable operating behavior and produces a reference current that has a negative temperature coefficient.

    • The method and system are used for recognising a time-sequential input pattern (20), which is derived from a continual physical quantity, such as speech. The system comprises input means (30), which accesses the physical quantity and therefrom generates a sequence of input observation vectors. The input observation vectors represent the input pattern. A reference pattern database (40) is used for storing reference patterns, which consist of a sequence of reference units. Each reference unit is represented by associated reference probability densities. A tree builder (60) represents for each reference unit the set of associated reference probability densities as a tree structure. Each leaf node of the tree corresponds to a reference probability density. Each non-leaf node corresponds to a cluster probability density, which is derived from all reference probability densities corresponding to leaf nodes in branches below the non-leaf node. A localizer (50) is used for locating among the reference patterns stored in the reference pattern database (40) a recognised reference pattern, which corresponds to the input pattern.
    • 该方法和系统用于识别从诸如语音的连续物理量导出的时间顺序输入模式(20)。 该系统包括输入装置(30),其访问物理量并由此产生一系列输入观察向量。 输入观测向量表示输入模式。 参考图案数据库(40)用于存储由参考单元序列组成的参考图案。 每个参考单元由相关参考概率密度表示。 树构建器(60)将每个参考单元的相关参考概率密度集合表示为树结构。 树的每个叶节点对应于参考概率密度。 每个非叶节点对应于簇概率密度,其从对应于非叶节点下方的分支中的叶节点的所有参考概率密度导出。 定位器(50)用于在存储在参考图案数据库(40)中的参考图案之间定位与输入图案对应的识别的参考图案。
