TJ Senior Research Project

Project Overview

The goal of my senior research project was to create a digital active crossover to filter an audio signal into frequency ranges ideal for different speaker drivers. My main tool for accomplishing this was a Field Programmable Gate Array (FPGA). The ultimate goal of the project was to take an analog audio signal input, convert it into a digital signal, filter it into two signals (one high frequency, one low frequency), convert those two signals back into analog, amplify the signals, and play them through a two-way speaker.
