This paper presents a method for designing the uni-directional array microphone with the same directivity and specified sidelobe size over the lower expanded wide-band by setting up the extremely large amplitude at the non-physical area in the 2-D frequency plane. 1-D FIR filters with the equiripple stop-band responses transformed Chebyshev polynomial are arranged on the cross sections in the 2-D frequency plane to compose to the objective amplitude of 2-D FIR filter. Design examples apparently show that the lower edge frequencies of the band are obtained less than that of the customary design. |
