本文图表内所列滤波器是从几百种计算机设计的滤波器中挑选出来的实用高通和低通滤波器。设计滤波器是件费时的工作而且需要专门知识。更兼设计出来的滤波器其电路还往往采用非标准元件。在要求不很严格的场合,数量不多的,预先设计的滤波器可以满足日常的需要。本文图表介绍了从计算机设计的滤波器中挑选出来的各种高、低通滤波器设计。这些滤波器的工作频率为1千赫至100兆赫,并采用标准电容器。
The filters listed in this chart are practical high-pass and low-pass filters selected from hundreds of computer-designed filters. Designing filters is a time-consuming job and requires specialized knowledge. Even the design of the filter circuit is also often non-standard components. In the case of less stringent requirements, a small number of pre-designed filters to meet the daily needs. This article presents a selection of high and low pass filter designs selected from computer-designed filters. These filters operate at frequencies from 1 kHz to 100 MHz and use standard capacitors.
