| 摘 要： | 本文介绍利用引入一个新的自变量Y(半时间带宽积)进入滤波器的频响计算公式中,可以很方便地利用预先计算好的表格、曲线设计所需要的滤波器。实践证明,理论与实际比较一致。

| Abstract: | This paper introduces a new method employing a new variable Y(half the time-bandwidth) in the frequency response calculation formula of SAWfilter, so that it is very convenient to synthesize a SAW filter with the desiredfrequency response using pre-calculated tables and curves. The experimental resultsshow a good consistence of theoretical analysis and practice. |
