# Errata for Lyons's DSP book

After reading the comments$^1$ and looking through various texts, I am going to use Understanding Digital Signal Processing for my self-study (Oppenheim & Wilsky was my 2nd choice). I'm 99% sure that a solutions manual doesn't exist. But does anyone know where I can find the errata for the 3rd edition?

I saw an old thread where the author, Dr. Richard Lyons offered to send it to someone so I can email him personally, assuming I can find his address. Before going that route, I figured that someone here may have it. Thanks.

• Richard is right here at DSP SE. He might actually answer your question. – jojek Oct 19 '17 at 21:51
• Oppenheim and Schaefer is more DSP than the book with Wilsky which is more Linear systems – Stanley Pawlukiewicz Oct 19 '17 at 23:10

• He might have gotten one in the last 10 years, I just didn’t know – Stanley Pawlukiewicz Oct 19 '17 at 23:49
• Hi Stanley: Thanks for heads up on difference between Oppenheim text and DSP. I tend to consider it all one topic but that's good to know. As far as Richard Lyons, I I don't know if he has one or not but I don't think it really matters either way. Anyone heard the other acronyms for B.S, M.S and Ph.D ??? I believe that a reasonably intelligent, passionate high school graduate could study one field for some period of time ( in time units of years of course ) and have as good a background as anyone else. Finally, as anyone with a Ph.D, already knows, not all Ph.D's are created equal !!!! – mark leeds Oct 20 '17 at 7:21
