Adaptive filters play a vital role in digital signal processing applications. In this paper, a new approach for the design and implementation of adaptive filters say FIR and IIR are analyzed. The filter design is based on least pth norm algorithm and the characteristics of the individual filters are also taken into consideration. Least pth norm algorithm is considered for the design because it ...

Simultaneous design of multiplier-free recursive filters (IIR filters) and their hardware implementation in Xilinx Field Programmable Gate Array (XC4000) is presented. The hardware design methodology leads to high performance recursive filters with sampling frequencies in the interval 15-21 MHz (17 bits internal data representation). It will be demonstrated that time-area eficiency and performa...

Signals in a two-channel quadrature mirror filter bank are decomposed into low and high frequency components. Similarly, analytic signals can be extracted from the original signal with only positive or negative frequency contents. Multirate systems based on this idea are called quadrature mirror Hilbert transformers. Just like the case of quadrature mirror filter banks, the FIR and IIR designs ...

5.1 INTRODUCTION Any action on a signal that modifies the spectral content of the signal is called filtering. This includes the enhancement or suppression of certain features of the signal and is usually achieved by the use of linear time invariant systems. There are situations where the system may change with time in a particular manner; such systems are called adaptive filters. In this sectio...

Signal processing engineers recognize two main classes of filter: finite impulse response (FIR) and infinite (IIR), each with distinct properties. The Prism is a new filter type that combines the best both: numerical stability linear phase FIR together low-cost calculation IIR. Here, we show how to build ultranarrowband filters containing over one billion samples (taps) using sequence Prisms. W...

Abstract— We present and discuss the structure and design of optimum multivariable decision feedback equalizers (DFEs). The equalizers are derived under the constraint of realizability, that is, causal and stable filters and finite decision delay. The design is based on a known dispersive discrete-time multivariable channel model, with infinite impulse response. The additive noise is described ...
