LEARNING MEDIA SIMULATION OF SIGNAL PROCESSING USING JAVASCRIPT PROGRAMMING LANGUAGE AS ALTERNATIVE TO DISTANCE LEARNING.

The main objective of this research is to create a signal processing simulation using Javascript programming language on acoustic waves. Signal processing uses Fourier Transform to convert signals from the time domain to the frequency domain. Acoustic wave samples were obtained from a Javanese music...

        The main objective of this research is to create a signal processing simulation using Javascript programming language on acoustic waves. Signal processing uses Fourier Transform to convert signals from the time domain to the frequency domain. Acoustic wave samples were obtained from a Javanese musical instrument called Gamelan. Acoustic wave signals from Gamelan are chosen because there is still little research on Gamelan signal processing. This research has successfully created a simulation using Javascript programming language. The simulation can show the waveform in function of time and its wave spectrum. The convenience of this tools for distant learning is substantiated.
        El objetivo principal de esta investigación es crear una simulación de procesamiento de señales usando el lenguaje de programación Javascript. El procesamiento de señales usa la transformada de Fourier para convertir señales del dominio del tiempo al dominio de la frecuencia. Se obtuvieron muestras de señales acústicas de un instrumento musical típico de Java llamado Gamelan. Se escogieron las señales acústicas del Gamelan porque aún existe poca investigación en su procesamiento. Hemos logrado crear una simulación usando el lenguaje de programación Javascript. La simulación es capaz de mostrar la forma de onda en el tiempo, y sí espectro. Se argumenta la conveniencia de esta herramienta para la enseñanza a distancia.
