	Fixed Point Representation and Fractional Math - The purpose of this paper is to investigate the issues relating to algorithm implementation utilizing fixed-point rather than floating-point mathematics.
	Narrow Band Filter Implementation On A Low Cost Microcontroller: Issues and Performance - The purpose of this project was to investigate the issues relating to the implementation of a digital filter on a low cost microcontroller platform rather than an expensive and special purpose Digital Signal Processor (DSP) system. In particular a 1KHz center frequency, 500 Hz bandwidth narrow band filter was implemented. Issues relating to sampling rate, fixed point mathematics, and signal reconstruction were observed and investigated. Overall system performance was also observed.
	Optimization of a Narrow Band Filter - Implementation On A Low Cost Microcontroller: Issues and Performance (paper) (presentation) - The purpose of this project was to investigate the issues relating to the implementation optimizations of a digital filter on a low cost microcontroller platform rather than an expensive and special purpose Digital Signal Processor (DSP) system. In particular a 1KHz center frequency, 500 Hz bandwidth narrow band filter was implemented. Issues relating to algorithm optimization, fixed point mathematics, sampling rate, and signal reconstruction were observed and investigated. Overall system performance was also observed.
	DC Motor With Inertia Disk Model Development, Proportional Controller, and State Feedback Controller with Full State Estimator - The purpose of this project was to develop a new mathematical model for a DC motor and verify its validity by implementing discrete controller on an Atmel AVR control system to compare theoretical performance with experimental performance.
	Advanced Digital Signal Processing Sidelobe Canceller (Beam Former) - The purpose of this project was to implement a DSP algorithm that could discern the direction an incoming signal was coming from utilizing an antenna array.
	Advanced Digital Signal Processing Adaptive Linear Prediction Filter (Using The RLS Algorithm) - The purpose of this project was to develop and adaptive linear prediction filter implementing the RLS algorithm and evaluate its performance.
	Advanced Digital Signal Processing Adaptive Linear Prediction Filter (Using the LMS Algorithm) - The purpose of this project was to develop and adaptive linear prediction filter implementing the LMS algorithm and evaluate its performance.
