多元信号最值检测器

An extremum detector with original circuit structure

介绍一种具有独特电路结构的多元信号最值检测器。该检测器将其输入端的多个信号电压进行比较，并指示出哪个输入端的信号电压最小或最大。检测器本身具有较高的分辨力，使彼此难以分辨的多个输入信号电压中的最大（小）者与其它输入电压间的差距在输出端加大变得易于分辨。当若干个这种检测器级联使用时，分辨力将大幅度提高。

n extremum detector with original circuit structure is introduced. The detector has N(N≥3) input terminals and (N≥3) output terminals. N input voltages applied to its N input teminals are compared each other inside the detector. and its output voltages indicate which input voltage is minimum (or maximum). This detector has higher resolution, which makes the differences difficult to distinguish between the minimum (or maximum) input voltage and the rest enlarged and distinguished easier. A detector derived from cascading a number of this kind of detectors has very high resolution.
