| 摘 要： | 讨论了有最小符号间干扰(ISI)的第一类部分响应滤波器的最佳设计方法。所设计滤波器的选择性和阻带衰减可预先给定并易于控制。以小的频带损失在Nyquist频率附近引入滚降,可使ISI进一步减小。利用这种滤波器还可以获得第四类部分响应信号。给出的设计实例说明这种设计方法很有实用价值。

| Abstract: | A method for optimal design of class 1 partial response filter with low intersymbol interference(ISI) is described. The filter selectivity and stopband attenuation can be easily specified or controlled. It is shown that ISI can be reduced by introducing roll-off around the Nyquist frequency at the expense of small spectral inefficiency. Class 4 partial response signals are obtained using class 1 partiae response filters. Design examples are given, which show that design method is appropriate for applications. |
