Polynomial-based Filters in Bandpass Interpolation and Sampling Rate Conversion
If the SRC is performed between arbitrary sampling rates, then the SRC factor can be a ratio of two very large integers or even an irrational number. An efficient way to reduce the implementation complexity of a SRC system in those cases is to use polynomial-based interpolation filters with the impulse response ha(t) having the following properties. ha(t) is nonzero for an interval 0 ≤ t < NT w...
متن کاملInteger Sequence Window Based Reconfigurable Fir Filters
Conventional hardware implementation techniques for FIR filters require the computation of filter coefficients in software and have them stored in memory. This approach is static in the sense that any further fine tuning of the filter requires computation of new coefficients in software. In this paper, we propose an alternate technique for implementing FIR filters in hardware. We store a consid...
متن کاملCascades of Polynomial-based and Fir Filters for Sampling Rate Conversion
where Fin = 1/Tin (Tin) and Fout = 1/Tout (Tout) are the original input sampling rate (period) and the sampling rate (period) after the conversion, respectively. The sampling rate conversion can be divided into two general cases. For R < 1, the original sampling rate is reduced and this process is known as decimation. For R > 1, the original sampling rate is increased and this process is known ...
متن کاملA Multiplierless Structure for Maximally Flat Linear Phase FIR Filters
A novel multiplierless structure for maximally flat linear phase FIR digital filters is proposed. The structure is based on a recursive evaluation technique for Bernstein polynomials. It consists of identical multiplierless building blocks connected in a regular fashion.
متن کاملA method for the design of Farrow-structure based variable fractional-delay FIR filters
This paper proposes a method to design variable fractional-delay (FD) filters using the Farrow structure. In the transfer function of the Farrow structure, different subfilters are weighted by different powers of the FD value. As both the FD value and its powers are smaller than 0.5, our proposed method uses them as diminishing weighting functions. The approximation error, for each subfilter, i...
