On the choice of band-pass quadrature filters
Web17 de jul. de 2015 · A complex quadrature charge-sharing (CS) technique is proposed to implement a discrete-time band-pass filter (BPF) with a programmable bandwidth of 20-100 MHz. The BPF is part of a cellular superheterodyne receiver and completely determines the receiver frequency selectivity. It operates at the full sampling rate of up to 5.2 GHz … Web1 de jun. de 2009 · Saptarshi Sengupta is an Assistant Professor of Computer Science at San Jose State University and a computational …

WebCommon applications. A common application in electronic music production is in the design of an effects unit known as a "phaser", where a number of all-pass filters are connected in sequence and the output mixed with the raw signal.. It does this by varying its phase shift as a function of frequency. Generally, the filter is described by the frequency at which the … http://www.cs.yorku.ca/~kosta/CompVis_Notes/quadrature_filters.pdf

Web1 de out. de 2014 · The α scale spaces is a recent theory that open new possibilities of phase-based image processing. It is a parameterised class (α ∈] 0, 1]) of linear scale space representations, which allows a continuous connection beyond the well-known Gaussian scale space (α = 1).In this paper, we make use of this unified representation to derive … WebThis article presents a versatile voltage-mode (VM) biquad filter with independently electronic tunability. The proposed structure using one dual-output operational transconductance amplifier, three single-output operational transconductance amplifiers (OTAs) and two grounded capacitors was explored to derive a new VM quadrature …
