一、序常用的分频器设计公式都是从实数形式列出的，没有考虑相位问题。因此常出现以下一些问题，如某音箱实测最低阻抗只有３欧姆左右；又如某音箱实测在某频率出现一峰值；再如设计时应按３ｄＢ交叉还是按６ｄＢ交叉。如何解释这些问题，及如何改进分频器设计。笔者使用... First, the sequence of commonly used divider design formulas are listed from the real form, did not consider the phase problem. So often some of the following problems, such as the lowest measured impedance of a speaker is only about 3 ohms; Another example of a speaker measured at a certain frequency peak; Another example is the design should be 3dB cross or 6dB cross. How to explain these issues and how to improve the divider design. I use ...
