This paper presents the methodology for the design of Low pass FIR digital filter using hybrid Differential Evolution (DE) method. It is an evolutionary algorithm that exhibits the features of both the basic DE and HookeJeeves exploratory move to attain the optimal solution. The basic DE and exploratory move have the capability to exploit and explore the search space to design the optimal filte...

a fundamental aspect of signal processing is filtering. Filtering involves the manipulation of the spectrum of a signal by passing or blocking certain portions of the spectrum, depending on the frequency of those portions. In this paper, Digital filters are designed using frequency specifications. Matlab provides different options for digital filter design, which includes function, calls to fil...

Abstract. According to recent literature, the most appropriate preprocessing to improve P300 detection is still unknown or at least there is no consensus about it. Research papers refer to different low-pass filters, high-pass filters, baseline, subsampling or feature selection. In this paper, using a database with 23 healthy subjects we compare the effect on the letter accuracy (single-trial d...

In this paper, the utilization of common fabrics for manufacturing e-textile metamaterial is investigated. The proposed design based on a transmission line loaded with split-ring resonators (SRRs) cotton substrate filter signal application. provides stop band between 2.7 GHz and 4.7 GHz, considering four stage SRR topology. Experimental results showed levels higher than −30 dB compact embroider...
