Este artículo desarrolla dos herramientas de síntesis de formas de onda de sonido, a saber, un sintetizador de tono y un generador de envolvente ADSR (Attack, Decay, Sustein and Release) para formar la amplitud del tono. Tales herramientas son codificadas en Matlab y programadas luego en la tarjeta p roces adora de señal DSP568ll de Motorola. Empleando la herramienta de síntesis musical de Matlab, previamente instalado en una computadora personal, nosotros podemos variar el período la forma de onda correspondiente a un instrumento, hasta dar con el tono preciso de dicho instrumento. Cabe anotar que las señales musicales así sintetizadas, se puede transmitir, por ejemplo, empleando módems.

El exoesqueleto es un sistema mecatrónico diseñado para mejorar las capacidades físicas y sensoriales de la persona al momento de asistir en una tarea específica, basado en la biología del tejido orgánico de los invertebrados esta estructura artificial posee la funcionalidad de ser un traje que recubre total o parcialmente el cuerpo del usuario. Gracias a ello, el presente trabajo de investigación propone la implementación de un diseño de sistema robótico a manera de exoesqueleto portable con cinco grados de libertad mediante el software de modelado en 3D SolidWorks y un sistema de control proporcional integrativo (PI) gobernadas por la metodología de cinemática directa trabajadas con las ecuaciones de movimiento de Euler- Lagrange dentro del software MATLAB el cual brindara el análisis y descripción de las trayectorias previamente programadas capaces de realizar las funcio...

This paper develops two synthesis tools for sound waveforms, namely, tone synthesizer and a ADSR(Attack, Decay, Sustein and Release) generator to form the tone amplitude. Such tools are coded in Matlab and programmed in a Motorola DSP568. By employing the musical synthesis tool of Matlab. previously installed into a personal computer, we are able to modify the period of a waveform sound corresponding to an instrument. It is worth to mention that musical sounds synthetized in this way can be transmitted by means of modems. 

The objective of this work is to explain the design, simulation and implementation of a vibrometer that could measure the oscillatory frequency of a particular structure in a wide range. The possibility of measuring a large frequency range is obtained with a simple change of the model in Simulink. The design of the electronic scheme proposed is implemented using the Arduino platform, planned and simulated with the Simulink tool of MATLAB, with the advantages that this philosophy reports in the design. This results in a low-cost electronic scheme that utilizes a magnetic switch as a very simple and cheap magnetic transducer. Considering that the scheme utilizes a low percentage of the Arduino, this might be used in other acquisitions and processing of a system.
