| Abstract(in English) | A cochlear filter bank for an audio band is used for an acoustic diagnostic, which detects broken points of a wall. However, for direct implementation of a cochlear filter bank by conventional FIR filters, the number of taps tends to be large. Thus, the amount of hardware increased. This paper proposes two methods to reduce the number of taps. The first one is to use a mixed analog-digital filter, which reduces the number of taps of the FIR filter. The second one is to apply a dynamic reconfigurable techniques which reduces the number of FIR filters. We implement the proposed one by the PSoC1 and the Spartan 6 FPGA. Experimental results showsed that the number of taps for the proposed one reduced to 1/107 comparing with a direct realization. Implementation of the acoustic diagnostic showed the usability of the proposed one. |
