چکیده

Zero-if transceivers suffer from the imbalance of the I and Q paths. By using a complex low-pass filter topology instead of a conventional pair of real low-pass filters, this imperfection can be reduced. Both analytical and numerical analysis show that the proposed technique is significantly more robust to circuit imperfections than the traditional architecture.

Utilization of an optimum low-pass filter during filtered back-projection in the reconstruction of single photon emission computed tomography images of small structures

Introduction:Low-pass filters eliminate noise, and accordingly improve the quality of filtered back-projection (FBP) in the reconstruction of single photon emission computed tomography (SPECT) images. This study aimed at selection of an optimum low-pass filter for FBP reconstruction of SPECT images of small structures. Material and Methods:Sp...

Improving the Performance of ICA Algorithm for fMRI Simulated Data Analysis Using Temporal and Spatial Filters in the Preprocessing Phase

Introduction: The accuracy of analyzing Functional MRI (fMRI) data is usually decreases in the presence of noise and artifact sources. A common solution in for analyzing fMRI data having high noise is to use suitable preprocessing methods with the aim of data denoising. Some effects of preprocessing methods on the parametric methods such as general linear model (GLM) have previously been evalua...

Sensorless Commutation of BLDC Motor without Low Pass Filter and Phase Shifter

 In this paper, a novel sensorless commutation method for BLDC motors is presented to simultaneously eliminate phase shifter and low-pass filter. An analytical model of the motor is presented and ripples resulted from the current commutation are investigated in detail. By detecting the zero crossing points of the unfiltered voltages of the motor terminals referred to the ground and DC link, the...

Sharpening Minimum-Phase Interpolated Finite Impulse Response Filters

This paper presents a novel simple method for the direct design of low-pass minimum-phase (MP) filters. The method is based on a linear-phase (LP) finite impulse response (FIR) prototype, sharpening and IFIR (interpolated finite impulse response) techniques, usually used for the design of LP filters. As a result, a more complex minimum phase filter can be designed by using less complex filters....

Wavelet Filter Functions, the Matrix Completion Problem, and Projective Modules over C(t N )

We discuss how one can use certain filters from signal processing to describe isomorphisms between certain projective C(T)-modules. Conversely, we show how cancellation properties for finitely generated projective modules over C(T) can often be used to prove the existence of continuous high pass filters, of the kind needed for multi-wavelets, corresponding to a given continuous low-pass filter....
