A Two-channel Hybrid Analog and Iir Digital Filter Bank Approximating Perfect Magnitude Reconstruction
نویسندگان
چکیده
This paper introduces a class of two-channel hybrid analog and IIR digital filter banks that approximates perfect magnitude reconstruction. It is an extension of a recently introduced class but that uses IIR instead of FIR synthesis filters. Using IIR filters the computational complexity can be reduced. This is demonstrated by means of an example. The filters are designed by making use of linear and non-linear programming.

متن کاملDesign of hybrid filter banks for analog/digital conversion
This paper presents design algorithms for hybrid filter banks (HFB’s) for high-speed, high-resolution conversion between analog and digital signals. The HFB is an unconventional class of filter bank that employs both analog and digital filters. When used in conjunction with an array of slower speed converters, the HFB improves the speed and resolution of the conversion compared with the standar...
متن کاملDesign of two-channel IIR linear phase PR filter banks
In this paper, a novel method is proposed for designing two-channel biorthogonal perfect reconstruction filter banks with exact linear phase using noncausal IIR filters. Since the structurally perfect reconstruction implementation is adopted, the proposed filter banks are guaranteed to be a perfect reconstruction even when all filter coefficients are quantized. From the view point of wavelets, ...
