To improve the middle frequency filter of communication system, This paper bases on 140 MHz band pass filter, and it discusses how to use Bessel function to design the precise band pass filter, simultaneously to stimulate the Bode graph and group delay character of the designed result with the newest software .and compares it with those existed, and find this pass band filter which designed with bessel function has the most practical applied value in these fields.
