Package for filter design based on MATLAB

Computer Applications in Engineering Education (2001)

D. Báez-López D. Baez-Villegas René Alcántara J.J. Romero T. Escalante

Abstract Electric filters have a relevant importance in electronic systems because they are present in almost any electronic system. For example, communication systems, as many other electric systems, make intensive use of filtering to separate unwanted noise from the desired signal. Unfortunately, filter design is an intensive computational task requiring a significant amount of numerical calculations to obtain either the parameters of a filter transfer function or the element values for a filter circuit realization. This paper describes a software package whose purpose is to provide a tool to be used as a teaching aid in analog and digital filter design courses. The feature of this package is that it uses MATLAB [ 2 ] for the numerical computations. The main advantage of the filter design software package described in this paper is that makes uses of one of the MATLAB toolboxes, the signals toolbox (which is used for analog and digital filter design), but used with an interface that makes possible even to the novice user to readily design filters, either analog or digital, without any previous knowledge of MATLAB or the signals toolbox. © 2002 Wiley Periodicals, Inc.

Design techniques for high-swing SC bandpass filters using telescopic OTA's

José Silva-Martínez D. Báez-López G. Gutierrez-Chave

A design technique to improve the swing of Telescopic OTA is presented. Using two common mode voltages, the DC levels in the input and output of telescopic OTA are modified. One example is presented showing the performance of the technique.

Direct determination of the coefficients of Chebyshev polynomials and other considerations

D. Báez-López Juan Manuel Ramírez-Cortés

A closed-form expression to obtain the coefficients of a Chebyshev polynomial is presented. This result allows direct determination of the coefficients of Chebyshev polynomials without requiring further algebraic manipulations or using recursion formulas. For even order, a closed formula is given when the Chebyshev polynomial is modified in such a way that the resulting even order low pass magnitude characteristic has a passive ladder realization with equal terminating resistances.< >

ProDIM: Educational software for digital image processing

Computer Applications in Engineering Education (1995)

Juan M. Ramírez Ramón A. García‐Aguilar D. Báez-López

Abstract We present the educational software package ProDIM, created with the idea of supporting courses on digital image processing techniques. This package was implemented in Visual Basic, which is a visual programming language to create applications in a Windows environment. Operations available in ProDIM include manipulation in the space and frequency domains, such as 2‐D convolution, gray‐level transformations, linear filtering, histogram equalization, and morphologic filtering. Examples show how the package can be useful as a lecture aid and as a lab assistance tool. The image to be processed can be generated using the editor included, or can be imported using images in a BMP format. A graphical interface allows the user to activate available operations through a menu selection.

Design considerations for very low sensitivity and very low round-off noise recursive digital filters

D. Báez-López C. Cabanas-Villa M. Hernandez-Apam

Sensitivity and round-off noise expressions for recursive fixed point digital filters are presented. These expressions can be used as design aids for the design of low-sensitivity and low-round-off noise recursive digital filters. The sensitivity and round-off noise analysis is carried out for four recursive topologies claimed to be low-sensitivity and/or low-round-off-noise topologies. The results show that, if one is looking only for a low sensitivity filter, the best one is the Agarwal-Burrus structure. But if one is looking for a low-round-off-noise structure for poles close to.< >

A Software Tool For Easy Introduction To TheUse Of Simulators In The Introductory CircuitTheory Courses

WIT transactions on engineering sciences (1970)

J. Ballesteros D. Báez-López

Circuit simulators play an important role in circuit design. However, their sintaxis is usually not friendy for students having their first exposure to this technology, causing reluctance toward the use of these kind of software aids. This fact was a driving force for the authors to propose a system by means of which the student could have access to a circuit simulator without having any knowledge about the sintaxis of it. In addition input/output to the system is in a graphic environment. In this way the student only has to specify as input the schematic diagram of his circuit and obtain as the output plots of the desired voltages and currents. The simulator chosen in this work can be anyone belonging to the family of SPICE simulators.
