This paper introduces a novel method named DEGL (Differential Evolution with global and local neighborhoods) regarding the design of two channel quadrature mirror filter with linear phase characteristics. To match the ideal system response characteristics, this improved variant of Differential Evolution technique is employed to optimize the values of the filter bank coefficients. The filter res...

The trend towards reconfigurable receivers requires on-chip flexible filters that can replace dedicated, bulky and non-tunable filters (e.g. SAW and BAW [1]). Although BAW filters are compatible with silicon processes, their center frequency is sensitive to thickness variation of the piezoelectric material and the achievable tuneability is limited [1]. Other techniques to make RF on-chip Band P...

This paper puts forward a brain computer interface (BCI) system to realize the hand and wrist control using ABB Mechanical Arm. BCI gathers four kinds of motor imaginary (MI) tasks (hand grasp, spread, flexion extension) electroencephalogram (EEG) signals from 30 electrodes. It utilizes two fifth-order Butterworth Band-Pass Filter (BPF) with different bandwidths normalization method achieve raw...

In this paper, a new miniaturized ultra-wideband bandpass filter is simulated. The structure of the new ultra-wideband bandpass filter is constructed using stepped-impedance resonator. The input admittance of the proposed filter is calculated and compared with the conventional structure. The frequency response of the filter is simulated by an EM simulator tool. The parameters of the proposed fi...

This paper presents an electronically tunable current-mode SIMO/MISO universal biquad filter using multi-output current controlled current conveyor transconductance amplifiers (MO-CCCCTAs). The proposed filter employs only two CCCCTAs and two grounded capacitors. The proposed configuration can be used as either single input multi-output (SIMO) or multi (three) input single output (MISO) current...

Characteristics of tunable wavelength pi’n/pin filters based on aSiC:H multilayered stacked cells are studied both experimental and theoretically. Results show that the device combines the demultiplexing operation with the simultaneous photodetection and self amplification of the signal. An algorithm to decode the multiplex signal is established. A capacitive active band-pass filter model is pr...

This paper presents a current-processing current-controlled universal biquad filter. The proposed filter employs only two current controlled current conveyor transconductance amplifiers (CCCCTAs) and two grounded capacitors. The proposed configuration can be used either as a single input three outputs (SITO) or as three inputs single output (TISO) filter. The circuit realizes all five different...

In this paper, an optimal design of linear phase digital finite impulse response (FIR) filter using Modified Particle Swarm Optimization (MPSO) has been presented. In the design process, the filter length, pass band and stop band frequencies, pass band and stop band ripple sizes are specified. Sometimes the gradient based optimization techniques are not effective for designing filter. An evolut...

The most important part of a Digital Signal Processing or DSP is a filter which passes the desired frequency components and rejects the unwanted signals as noise. So Digital filter play an important role in DSP based communication system. Digital filter has many advantages over the analog filter. FIR filter gives linear and stable performance as compare to IIR filter. In this paper Band reject ...

Improvement of Analog-to-Digital Converters testing method that is suitable for testing of high-resolution AD converters (e.g. Σ-∆ or dither-based) or on the contrary ultra high-speed AD converters is presented. The method is based on the histogram test driven by stochastic signal with defined probability density function. By repeating of the test for different settings of band-pass filter that...
