ANÁLISIS DE RUIDO DE COLORES EN UN CIRCUITO RLC SERIE DE FORMA EXPERIMENTAL (COLOR NOISE ANALYSIS IN A SERIAL CIRCUIT RLC EXPERIMENTALLY)
Resumen
La contribución principal de este trabajo es determinar el color del ruido de forma experimental analizando la densidad espectral de potencia (PSD) de una señal medida en un sistema eléctrico, para esto, se generan y simulan los ruidos de colores (blanco, rosa, rojo, azul y violeta) mediante el software Matlab para alimentar a un circuito RLC serie y analizar el color de ruido presente, lo anterior se realiza en cuatro escenarios diferentes: Ruido, Fuente de Señal CD + Ruido, Fuente de CA + Ruido y Fuente de CD + CA + Ruido, las mediciones se realizan con un sistema de adquisición de datos y el software LabVIEW. Los resultados obtenidos identifican que los ruidos de colores generados y medidos tienen el mismo comportamiento, además, se presentan los resultados de medir el circuito RLC alimentado con solo una fuente de CD para identificar el ruido de color presente en el sistema.
Palabras Clave: Circuito RLC, Densidad Espectral de Potencia, Ruido de colores.
Abstract
The main contribution of this work is to determine the noise color experimentally by analyzing the power spectral density (PSD) of a signal measured in an electrical system, for this, colored noises (white, pink, red, blue, and violet) are generated and simulated using Matlab software to feed a serial RLC circuit and analyze the noise color present, the above is performed in four different scenarios: Noise, DC Signal Source + Noise, AC Source + Noise and DC Source+ AC Source+ Noise, the measurements are performed using a data acquisition system and LabVIEW software. The results obtained identify that the generated and measured color noise have the same behavior, in addition, the results of measuring the RLC circuit powered with only a DC source are presented to identify the color noise present in the system.
Keywords: Noise Colors, Power Spectral Density, RLC Circuit.
