Unformatted text preview: UCLA Dept. of Electrical Engineering EE 114, Winter 2009 Computer Assignment 1: Introduction to Frequency Analysis EE 114 Computer Assignment Report Format : When completing computer assignment reports, we recommend that you start each with an abstract, consisting of one or two paragraphs, which provides a high level summary of the assignment. Proceed by answering the questions listed in the assignment and include any code that you write. Please work in groups of 2 students and submit 1 report per group. Introduction : The goal of this assignment is to serve as an introduction to frequency analysis using MATLAB. Specifically, this assignment deals with implementing and applying the Discrete Fourier Transform (DFT) to speech signals. Download the computer assignment 1 supplementary files (” ca 1 files.rar ”) from the eeweb course website, and uncompress them. Run the first program by typing ”one” at the MATLAB prompt. Two figures should be displayed. The first figure will include the entire sentence ”she had your dark suit in greasy wash water all year” in the top panel, and the word ”wash” in the bottom panel....
