摘　　要：从理论上分析了四种欧拉映射离散时间积分器的频域特性和这四种映射的适用条件 。In this paper, the frequency characteristics of four kinds of Euler mapped discrete time integrators are analysed theoretically and the operation conditions of these mapping are also indicated. Some valuable conclusions that should be considered in designing switched capacitor and switched current filters are given.$$$$
