Introduction to Real-Time
Digital Signal Processing
Signals can be divided into three categories ± continuous-time (analog) signals,
discrete-time signals, and digital ... On the other hand, digital signals have discrete
values in both time and amplitude. In this book, we design and implement digital
systems for processing digital signals using digital hardware....
