Abstract本实用新型涉及一种模拟信号处理的技术,具体地说是一种极值采样电路。本实用新型包括选通电路、采样保持电路和射随电路;所述选通电路的输入端输入视频输入信号和选通信号,在选通信号使能的情况下输出选通条件下的视频输入信号;所述采样保持电路的输入端输入所述选通条件下的视频输入信号,获得窗口内幅值最高的信号幅值,即极值信号;所述射随电路的输入端输入极值信号,用于输出所述极值信号。采用本实用新型可以有效提取给定范围内的信号极值;采用本实用新型可以灵活选择选通范围;本实用新型结构简单,使用方便。
Other AbstractThis utility new type relates to a simulate signal processing of one technology, specifically a one extreme value sampling circuit. This utility new type comprises a gating circuit, sampling maintain circuit and radio with circuit, the input end of said gating circuit input video input signal and gating signal, the energy of the gating signal output gating condition of video input signal, a sampling maintain input end of input circuit of video input signal at a gating condition, obtain the window in the high amplitude of signal amplitude, the extreme value signal, a radio-frequency input end of circuit input extreme value signal, which is used for output said extremum signal. Using this utility new type can be valid within a given range of extraction signal extreme, using this utility new type can be flexibly selecting gate range, the utility model is new type has simple structure and is convenient to use.
