General-Purpose Digital Filter Platform, Michael Cheng
General-Purpose Digital Filter Platform, Michael Cheng
Electrical Engineering
This senior project provides a platform for high-speed, general-purpose digital filter implementation. EE 459 currently implements digital filters using reprogrammable digital signal processor boards. These aging digital signal processors serially calculate each difference equation term. Operating at 1 Mega-sample per second, the new general-purpose platform simultaneously processes at least ten digital filtering difference equation coefficients. The platform also features an audio jack input and BNC connectors for viewing input and output signals. The filter digitizes single channel audio signals at 44.1 kHz sampling rate with 16-bit precision or 1 MHz sampling at 8-bit precision. The new reprogrammable platform includes a …

The Visual Representation Of Sound For The Hearing Impaired, Jonathan Brophy
Electrical Engineering
There are many difficulties that arise when one is faced with a hearing disability. New applications of advancing technology have the potential to enable designs capable of assisting the hearing impaired with the ability to see sound. This project seeks to provide a user with a visual representation of loud noises detected using small directional microphones. The microphones determine the location of the sound above a set decibel level and a microprocessor determines the approximate location of the sound source and displays a vertical colored bar on a video image in the direction of the noise using virtual reality glasses. …

Discrete Alarm Clock, Travis Moore, Collin Barth
Electrical Engineering
The standard alarm clock, as used daily by millions worldwide, has clear room for modification and improvement. This paper documents an implementation that rectifies many of these flaws. Improvements include adjustable snooze length, an IR remote for ease of use, and an RF headset for discrete alarm use or potential incorporation into a device much like a hearing aid. The processes involved in creating a digital alarm clock, as well as the obstacles met in the implementation of the enhanced design, are detailed within.
