A sixth-order low-pass gm-C filter with a very wide tuning range (fc = 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...

In this paper we derive convolutional filters for colour image whitening and decorrelation. Whilst whitening can be achieved via eigendecomposition of the image patch covariance, this operation is neither efficient nor biologically plausible. Given the shi ...
This paper introduces an easy-to-use decision support system for COllabOrative DEsign named CO2DE. We examine the system particularly for the design concept filtering and selection stages considering the importance of conceptual design although the propose ...
A reconfigurable bandpass filter able to switch between WiFi and UMTS reception standards is presented. The topology allows achievement of two accurate centre frequencies, each associated with a precisely defined bandwidth, using six pin diodes. The design ...
We propose a framework for blind multiple filter estimation from convolutive mixtures, exploiting the time-domain sparsity of the mixing filters and the disjointness of the sources in the time-frequency domain. The proposed framework includes two steps: (a ...
The ever increasing demand for large quantities of bio-engineered pharmaceuticals and the tendency for doses to become larger stimulate the development of more productive and reliable mammalian cell culture technologies. In this context, perfusion bioreact ...
This paper presents wideband tunable band-stop filters working in the Ku to Ka-band frequencies based on a miniature single-MEM device combining a central capacitive MEM switch with AlN dielectric and inductive suspension arms. An outstanding 55% tuning ra ...

We study analytically pulse distortion in linear slow light systems, and provide some useful limits on these devices. Additionally, we also show that the contributions of phase and amplitude broadening can be de-coupled and quantified. It is observed that ...
In this paper a reconfigurable bandpass filter able to switch between WiFi and UMTS transmit band standards is presented. The filter is designed in such a way that center frequency and bandwidth specifications are precisely met by defining a switchable fil ...
Interpreting measurement data to extract meaningful information for damage detection is a challenge for continuous monitoring of structures. This paper presents an evaluation of two model-free data interpretation methods: moving principal component analysi ...
