Digital Filter Design Using Non-Uniform Sampling

In this paper, a non-uniform sampling algorithm is proposed for one-dimensional bandlimited time varying signals. The main feature of the proposed sampling scheme is that the sampling steps are inversely proportional to signal gradient or slope of the signal. As a result, a smaller sampling step is obtained whenever the gradient is high and vice-versa. Thus, a better representation of the signa...

Design and implementation of a Multiplier-Less VLSI Architecture using Wavelet Filter Banks

Wavelet based signal processing incorporating Hilbert transform pair is proved to be more efficient by many authors. The multiplier-less VLSI based architecture of wavelet filter bank for biomedical applications is being proposed in this project. The proposed architecture reduces the computational complexity and improves the performance by combining DWT, Hilbert transform and sampling. Multipli...

Design of Multiplier-less Cosine Modulated Filter Banks with Sharp Transition using Evolutionary Algorithms

This paper proposes a totally multiplier-less approximate reconstruction cosine modulated filter bank. The prototype filter is designed to obtain a computationally efficient, sharp transition width, finite impulse response (FIR) filter using the frequency response masking (FRM) approach combined with the canonic signed digit (CSD) representation of the coefficients. Meta-heuristic algorithms ar...

Design of Multiplier-less Sharp Transition Width MDFT Filter Banks using Modified Metaheuristic Algorithms

The significant advantage of modified discrete Fourier transform (MDFT) filter banks over the conventional discrete Fourier transform (DFT) filter banks is the structure inherent alias cancellation in the former. When the number of channels is increased, the filters in the filter bank need to be of sharp transition width. This increases the complexity of the filters and hence that of the filter...

Efficient interpolators and filter banks using multiplier blocks

We examine the use of efficient shift-and-add multiplier structures and multiplier blocks to reduce computational complexity in filter banks. This is more efficient than treating each bank filter separately. We also examine the Farrow structure, which is used in interpolators. Applying multiplier blocks makes this structure cheaper than the more recognized Lagrange interpolator.
