| 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。

| Abstract: | 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 demonstrates 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. |
