摘要
研究和探讨了基于采样保持器的滤波电路———采样保持滤波SHF电路,即利用采样保持器的采样保持特性,对某些特定波形模拟信号进行滤波处理。理论分析表明,这种SHF电路是可行的;实验仿真也证实,相对于传统的有源RC滤波电路,这种SHF电路具有更优异的处理效果。SHF电路结构在一定程度上解决了有源RC滤波电路对某些特定信号处理不足的问题。
Studies are made on the filter circuits based on sample-and-hold amplifier （SHA）, in which the sample and hold property of SHA is utilized to filter analog signals with special waveforms. Theoretical analysis demon strates its feasibility. Experimental results also prove that, compared with traditional active RC filter circuits, the sample-and-hold filter （SHF） circuits have better performance. SHF circuits eliminate the deficiencies of the active RC filter circuits in dealing with some special signals.
