GENERACIÓN DE SEÑALES SENOIDALES MEDIANTE PWM Y FILTROS ACTIVOS DE SEGUNDO ORDEN Sinusoidal Signal Generation using PWM and Second-Order Active Filters

This document presents the results obtained when designing a system capable of generating sine wave from PWM, based on microcontroller and second-order active filters. The study started in software development that generates the wave pulse width modulated by the microcontroller, continuing with the design of active filter second order Sallen-Key configuration, through simulations in Proteus®, and ending with implementation in protoboard.
