With the advent of finer and finer line integrated circuit technology, it is becoming difficult to use purely analog circuits to design filters and several other analog functional blocks. Digital filters can be used to fill the gap in such applications. Finite impulse response, or FIR digital filters are an important class of digital filters that are extensively used. This book presents an easier and practical technique to design and simulate these filters. The approach is simple and the descriptions are very clear. Practicing engineers and students will benefit from the contents of this book as it is targeted for busy professionals and helps to develop the circuits with a minimal of time spent on researching and fretting over the design. The CAD tools that have been recommended and introduced help greatly in this effort. Most of the CAD tools that have been listed are free of cost and yet very effective.
