This paper proposes a realization method of high accuracy 2-D variable IIR digital filters with real coefficients. The proposed method uses the reduced-dimensional decomposition form as a prototype structure of 2-D variable digital filters to suppress the degradation of tuning accuracy due to the linear approximation of variable coefficients. Furthermore, the 1-D subfilters of the prototype fil...

The FPGA (Field Programmable Gate Array) constitute of many programmable modules like Configuration Logic Blocks (CLBs), Block Random Access Memories (BRAM), DSP 48 blocks and Input/output (I/O) modules. The CLBs are the main programmable logic units which consist of different number of logic slices and each slice contains different number of LUTs and flips flops depending upon the FPGA device ...

Abstract—The design problem of Infinite Impulse Response (IIR) digital filters is usually expressed as the minimization problem of the complex magnitude error that includes both the magnitude and phase information. However, the group delay of the filter obtained by solving such design problem may be far from the desired group delay. In this paper, we propose a design method of stable IIR digita...

Abstract-Electrocardiogram (ECG) signal has been broadly used in cardiac pathology to find heart disease. ECG signal is commonly corrupted by disparate artifacts as baseline wander, power line interference (50/60 Hz) and electromyography noise and these should be eliminated before diagnosis. The function proposed in this paper is removal of low frequency interference i.e. baseline wandering and...

-The paper develops innovative methodology for the robust and stable design of digital infinite impulse response (IIR) filters using predator-prey optimization (PPO) method. Predator-prey optimization is undertaken as a global search technique and exploratory search is exploited as a local search technique. Being a stochastic optimization procedure, PPO technique, avoids local stagnation as pre...

A decision feedback equalizer (DFE) containing a feedback filter with both poles and zeroes i s proposed for high-speed digital communications over the subscriber loop. The feedback filter is composed of two sections: a relatively short finite impulse response (FIR) filter that cancels the initial part of the channel impulse response, which may contain rapid variations due to bridge taps; and a...

Introduction This application note describes the implementation of digital filters in the Atmel AT6000-series FPGAs. Bit-serial digital signal processing is used to construct efficient Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filter macros that can be cascaded to create higher-order functions. We will briefly review the techniques first introduced in the application not...
