ME57900 - Fourier Methods in Digital Signal Processing

Spring 2016

Days/Time: TBA / TBA
Credit Hours: 3

Learning Objective:
To familiarize the student with functions found in most frequency analysis software, introduce the basics of digital filtering and digital filter design, introduce basis of stationary signal analysis and derive input-output relationships for linear time-invariant systems.

Alternate Title: Fourier Methods in Digital Signal Processing
Fundamentals of signal processing associated with Fourier analyzer systems are presented. Emphasis is on amplitude accuracy and frequency resolution properties necessary for reliable experimental methodologies in system identification, spectrum estimation, and correlation analysis. Deterministic as well as random data analyses are presented.

Topics Covered:
Engineering applications of Fourier analysis of signals, both random and deterministic; Digital Filtering; Spectral estimation; Transfer function estimation; Coherence; Effects of measurement (windowing, sampling, noise); Strategies to minimize adverse effects and to facilitate meaningful interpretation of data analysis results

Undergraduate treatment of Laplace transforms, Fourier series, basic statistics.

Applied/Theory: 30/70

Web Address:

Five to seven homework assignments, each consisting of 5 to 7 questions. Please keep each problem separate, i.e. start a new problem on a new sheet of paper, and make sure your name and the problem set and problem number are on each sheet of your solutions.


One midterm exam and one final exam.

Required-None. List of recommended reference texts will be provided with the course syllabus.
