University of Central Florida School of Electrical Engineering and Computer Science EGN-3420 - Engineering Analysis. Fall 2009 - dcm Homework 5 due Thursday week 13 (100 points) Problems 1-10 (10 points each) Solve problems: 11.2 (page 261); 11.10 (page 262); 12.6 (page 279); 12.10 (page 280); 13.3 (page 312); 13.24 (page 314); 14.2 (page 332); 15.10 (page 357); 16.3 (page 386); 16.6 (page 387); Extra credit problem (10 points for boundary grade considerations) 1. Display an audio waveform and its spectrum Audio signals, much like images, can undergo filtering. It is somewhat easier to understand the impact of signal processing on audio, since audio needs not be translated from a spatial to a frequency domain. To load a wave (PCM) audio file, Matlab provides the function wavread . For example: kiki = wavread(’kiki.wav’); To capture the sampling frequency at which the sound was recorded,use: [kiki, f] = wavread(’kiki.wav’); otherwise the speed of playback and results of further processing is not guaranteed to be correct.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
