Preface

Over the years, I have published a large number of DSP tutorials on various websites. This collection, which is a work in process, gathers the moresignificant of those tutorials into a common location to make them more readily available for Connexions users.

Some of the tutorials were originally published ten or more years ago. However, you need not be concerned about the material in those tutorialsbecoming obsolete. The concepts and algorithms involved in DSP (such as convolution, correlation, the discrete Fourier transform and the Fast FourierTransform) are essentially the same today as they were when they first became practical for use on digital computers around 1960. (However, the hardware used to implement those algorithms has become much smaller and muchfaster.)

As I have time available, I am converting the tutorials from their original HTML format into the Openstax format that you are accustomed to seeing. You willfind that some of the tutorials are available in Openstax format, and others are available in HTML or PDF format as described below.

Legacy versus openstax presentation format

Early in 2014, cnx.org began a transition from a legacy presentation format to a new openstax presentation format. As of October 8, 2015, some ofthe functionality of the legacy presentation format that is required by modules in this collection have not yet been ported to the openstax presentation format. (In particular, image files referenced by hyperlinks in HTML versions of thetutorials may not display properly in the openstax presentation format.)

This issue should be resolved at some point in the future. In the meantime, one of your options is to select and view the PDF versions of the tutorials using the PDF links that are provided.

A second option is to click the Legacy Site link at the top of this page (assuming that you are not already on the Legacy Site) and view the tutorials in their original HTML format. (The HTML format is more reliable than the PDF format, particularly with regardto source code listings.)

Later, when the issue mentioned above is resolved, you can select either the PDF versions or the HTMLversions directly from the openstax presentation page, whichever you prefer.

Financial : Although the openstax CNX site makes it possible for you to download a PDF file for the collection that contains thismodule at no charge, and also makes it possible for you to purchase a pre-printed version of the PDF file, you should beaware that some of the HTML elements in this module may not translate well intoPDF.

You also need to know that Prof. Baldwin receives no financial compensation from openstax CNX even if you purchase the PDF version of the collection.

In the past, unknown individuals have copied Prof. Baldwin's modules from cnx.org, converted them to Kindle books, and placed them for sale on Amazon.com showing Prof. Baldwin as the author.Prof. Baldwin neither receive compensation for those sales nor does he know who doesreceive compensation. If you purchase such a book, please be aware that it is a copy of a collection that is freelyavailable on openstax CNX and that it was made and published without the prior knowledge of Prof. Baldwin.

Affiliation : Prof. Baldwin is a professor of Computer Information Technology at Austin Community College in Austin, TX.

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

A ball is thrown straight up.it passes a 2.0m high window 7.50 m off the ground on it path up and takes 1.30 s to go past the window.what was the ball initial velocity

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
