This paper presents a novel approach for designing a linear phase digital high pass FIR filter using Improved Particle Swarm Optimization (IPSO) algorithm. Design of FIR f ilter is a multi-modal optimization problem. The conservative gradient based optimization techniques are not efficient for digital filter design. Given the specifications for the filters to be realized, IPSO algorithm generat...

The digital filter implementation in FPGA,utilising the dedicated hardware resources can effectively achieve ASIC-like performance while reducing development time cost and risks.

In this paper a low pass,band pass and highpass FIR filter is implemented on FPGA.This ...

This paper consists of design of digital FIR high pass filter using predator prey optimization and hybrid predator prey optimization (HPPO) technique. HPPO is a combination of predator prey optimization (PPO) and exploratory search where Predator prey optimization is a global search method and exploratory move is a local search method. Local stagnation is possible in PSO but there is no local s...

This paper presents the development of highly integrated millimeter waves function in multilayer LTCC and Liquid Crystal Polymer technology. Both ceramic and organic technologies are candidate of choice for the 3D integration, following the system-on-package concept, of compact, low cost, millimeter-wave high data rate wireless systems. Compact and easy-to-design passive functions such as direc...

A simple but efficient stereo reverberation control is developed to simulate reverberation. Inspired from previous classic studies, the reverberator is built using simple digital filters, including comb filters and all-pass filters commonly used for digitally simulating reverberation. The digital reverberator incorporates low-pass filters to simulate the air and walls absorption effect, gains t...

A new resistorless single-input-multi-output (SIMO) universal transadmittance (TA) type filter employing two voltage differencing transconductance amplifiers (VDTA) and two grounded capacitors is proposed. The proposed topology realizes simultaneously low pass (LP), high pass (HP), and band pass (BP) filter functions. Band rejects (BR) and all pass (AP) filters are also realizable through appro...

A thin-film optical filter used as a one-dimensional spatial filter is presented, and its design is briefly examined. The filter consists of a stack of quarter-wave dielectric layers upon a right-angle prism that selectively cancel a reflected or transmitted plane-wave front for various angles of incidence. Transmittance and reflectance are low-pass functions or high-pass functions of the angle...
