We discusses the application of the neural networks in the field of FIR(finite impulse response) band-block filters with linear phase. The linear-phase band-block filters are designed by the neural networks, which characteristic of the amplitute-frequency is no excess-impulsion and ripple. Its attenuation performance is very good and over 100dB in the block-band. The example of the FIR band-block filter with a lineary-phase is presented. The result shows that the algorithm is efficient and excellent in the design of the FIR filters.
