使用在线电子表格,设计人员可从一个通用滤波器传递函数推导出最常见的滤波器类型。当一定复杂程度的信号通过几乎任何电子系统时,它都需要某种滤波——经常是多种类型的。但许多以数字电路背景为主的设计人员在对付模拟滤波器时会犹豫不决,因为他们在大学时代有过对滤波器极点与零点进行复杂分 Using an online spreadsheet, designers can derive the most common filter types from a common filter transfer function. When a signal of some complexity passes through almost any electronic system, it needs some kind of filtering - often multiple types. But many digital circuit-based designers are hesitant to deal with analog filters because they had complicated points in their college days with filter poles and zeroes
