Handbook of Formulas and Tables for Signal Processing (Electrical Engineering Handbook)

This book contains various subjects for signal processing and, excellent collection of SP data, and has been a great help for me to memind the very mathematical expression and formula which i can not figure out on my head. Most impressive factor to me was the arranged list of formulas which you've never found in any SP book. This book would be used for quick reference for signal processing technology, and if you are in the front part of signal processing technology, you may need to use many of the formulas, so, it will be a great help for your task such as writing a technical paper, finding a proper use of formula, understanding quickly on a mathematics-related subjects and so on. It might be one of essential books that you can find on your bookshelf for a long time.
