Summary

This three-day course is the beginner's best opportunity to efficiently learn DSP. Intuitive, nonmathematical explanations and well-chosen examples develop the student's fundamental understanding of DSP theory. The practical aspects of signal processing techniques are stressed over discrete system theory. Participants will leave with a collection of tricks-of-the-trade used by DSP professionals to make their processing algorithms more efficient. Public course attendees will receive a copy of the book - Understanding Digital Signal Processing by Rick Lyons

Learning objectives

Upon completing the course you will be able to:

Apply DSP techniques to real-world signal acquisition, spectral analysis, signal filtering, and quadrature processing problems.
Fluently speak the language of DSP.
Understand written descriptions (articles, application notes, textbooks) of common, practical DSP techniques.
Obtain further DSP information using a comprehensive list of references.

Target Audience

Practicing RF hardware engineers and technicians, and computer programmers seeking an understanding of DSP technical theory and algorithms will benefit from this course. The course does not cover the internal architecture of commercial DSP integrated circuits.

Great presentation of a complex subject. I will leave here with the knowledge on how to go about designing a DSP system. Rick is a great instructor. C.I.

The material and the method in which is was presented was extremely beneficial to provide a more intuitive understanding of DSP. W.L.

I enjoyed how each component of the key components were explained in detail before they were presented as a whole to the class. I also liked how Lyons would provide practical examples as to how the material is implemented. R.Z.

The course offered great non-mathematical studies of DSP and covered exactle what the description marketed the class as. Rick was a fantastic teacher, his enthusiasm and experience made this a great class. The class size was perfect and the location was one of the best for traninings that I've had. J.L.

Instructor was able to easily tie related concepts together and associate them with practical real-world applications. I felt like I had gone through an excellent review of the mathematics I learned in my last two years of college! Instructor was also generous and accommodating of questions. L.G.

Richard Lyons is a wonderful instructor that communicates his ideas and information in the multi-faceted ways that are absolutely necessary to truly teach a topic. I.F.

I liked the way the instructor explains every concept. Easy to understand. No suggestions for improvement - excellent course! A.R.

A very good minimal math intro to DSP from someone who had done it in the field but was not claiming to be a complete expert. He seems very down to earth and pragmatic. B.D.

Complex materials were explained in clarity. Excellent job. R.M.

I liked the basic content and pace, practical approach and the instructor's intent on providing a non-threatening way of learning complex subject matter. Inviting and interactive environment where questions and dialog is encouraged. C.S.

I liked the instructor's ability to make a complex topic very easy to understand. Rick has the ability to explain very complex mathematical concepts very simply! Allen Hollister Plantronics

Rick is very interested in us understanding the material and it comes across.

The instructor explained concepts using real world examples. This was an excellent approach and I understood everything explained.

The course material clarified a lot of my misinterpretations. Rick was excited (great positive attitude) toward his presentation.

I found the course well tuned and just about perfect for my needs. Any more "AHA!" moments and I'd be in real trouble from overload. R. Osman

I liked everything in the course. This course is an excellent refresher course for engineers, especially to those who are new to DSP.

I liked the easy to understand step by step approach.
