Derivation of Oscillators from Biquadratic Band Pass Filters Using Circuit Transformations

open access: yesApplied Sciences, 2014
Network transformations are the techniques to obtain new functional schemes from available circuits. They are systematic methodologies, since each transformation technique can be applied to many circuits to obtain the desired functions or characteristics.

Efficient reconstruction of band-limited sequences from nonuniformly decimated versions by use of polyphase filter banks [PDF]

open access: yes, 1990
An efficient polyphase structure for the reconstruction of a band-limited sequence from a nonuniformly decimated version is developed. Theoretically, the reconstruction involves the implementation of a bank of multilevel filters, and it is shown that how

Tunable Active Band-Pass RC-Filter

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2018
This article provides a technique for design and simulation of an active second order band-pass filter with lineal tuning of Q-factor and independent tuning over a wide range of resonant frequency and transfer coefficient. The tunable band-pass RC-filter

A Novel Band-Stop Filter with Band-Pass, High-Pass, and Low-Pass Negative Group Delay Characteristics

open access: yesInternational Journal of Antennas and Propagation, 2021
A band-stop filter with three different negative group delay functions in the passband, namely, band pass, high pass and low pass, is proposed, which has small insertion loss. The capacitance, inductance, and resistance meet different conditions, and the

Band-Pass filters using OSRR cells

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2015
This paper presents the design process (including optimization and characterization) of a band-pass filter through the use of OSRR-structured meta-material cells over micro-strip substrates. The proposed design, which stems from the OSRR cell model, includes a partial ground plane etched at the bottom plane instead of, and square windows etched at the ...

Hanning FIR window filtering analysis for EEG signals

open access: yesBiomedical Analysis
The window function is a mathematical function in signal processing that is multiplied by a signal to lessen or eliminate the impact of undesired characteristics such as spectral leakage and edge effects that might arise while analyzing finite-duration ...

Design of Ka Band Bandpass Filter Based on Radial Stub

open access: yesTaiyuan Ligong Daxue xuebao, 2023
Purposes In communication systems, filters play an important role in filtering out-of-band signals. For the traditional parallel coupled line filter and clip line filter, the size is large and the parasitic pass band problems exist.

Observation of flat chaos generation using an optical feedback multi-mode laser with a band-pass filter.

open access: yesOptics Express, 2019
We demonstrate experimentally that flat and broadband chaotic signals can be easily generated by combining a multi-mode laser diode subject to optical feedback with a band-pass filter. Measurements are made of the RF spectra of multi-mode and single-mode
