A digital filter can be pictured as a “black box” that accepts a sequence of numbers and emits a new sequence of numbers. In digital audio signal processing applications, such number sequences usually represent sounds. For example, digital filters are used to implement graphic equalizers and other digital audio effects. This book is a gentle introduction to digital filters, including mathematical theory, illustrative examples, some audio applications, and useful software starting points. The theory treatment begins at the high-school level, and covers fundamental concepts in linear systems theory and digital filter analysis. Various “small” digital filters are analyzed as examples, particularly those commonly used in audio applications. Matlab programming examples are emphasized for illustrating the use and development of digital filters in practice.
This is a great book. I’ve only worked my way about 1/2 way through it so far, but it gives a perfect balance of practical and theoretical background so real engineers can get real work done. For the areas it covers, this book is much more understandable than Oppenheim And Schafer. For the areas it doesn’t cover, it’s still more understandable though a little less informative.
The great thing about this book is that it gives you pointers to real tools and real implementations for getting work done (i.e. lots of matlab examples, c examples, etc).
It’s a bargain at twice the price.
