摘要
分析了Ｎ×Ｎ内部无阻塞输入／输出排队ＡＴＭ反压型交换机在多优先级独立负载输入，加速因子Ｓ≥Ｂ（输出缓冲容量）的情况下，各优先级业务通过交换机的平均延时。计算机仿真结果表明理论分析是正确的。
A novel design method of surface acoustic wave(SAW) bandpass filter is discussed.After resampling at the interval of M ,the original desired weighting function is decomposed into two weighting functions with less order by the zero separating of Z transform,and then represented by interpolation derived from the signal reconstruction theory and can be furtherly suboptimized using the standard Remez change method.The simulation results of a Blackman spectrum shaping filter with the center frequency of 70 MHz,the roll off factor of 0.19,0.35 dB ripple,67 dB rejection,confirm that this method is very simple and effective.
