| Abstract: | A new method of SAW filter designing is presented,i. e,digital Fourier transforming method. This method has a higher calculating accuracy of frequency response than the normal wethods, and coincides with theoretical results botter. So it is suitable for various SAW filters' designings in the information processing system, with different frequencies, symmetrical and nonsymmetrical freqresponses, linear and nonlinear phrases, high low impedances and different bandwidths. |
