| Summary: | 碩士 === 國立交通大學 === 電信工程系 === 90 === This thesis describes the compensation of the distortion in the transversal SAW filter due to diffraction effect.The origin of the diffraction phenomenon is presented and the mathematical model of the diffraction response is established. Several compensation methods which are classified into in time domain and frequency domain are evaluated. Accordingly, a computer program with effective algorithm is developed.Its capability is demonstrated in the design of an IF bandpass filter applied in Digital Audio Broadcast(DAB).
