In this paper, we suggested a 490Khz crystal narrow band pass filter that is equivalent circuits of for NAVTEX receiver, and simulated with the PSpice to get the optimized parameters of frequency response property of the crystal filter. After that, it was produced as computer simulation results and estimated the performance of filter.
