Chapter Thirteen. Digital Signal Processing Tricks
As we study the literature of digital signal processing, we'll encounter some creative techniques that professionals use to make their algorithms more efficient. These practical techniques are straightforward examples of the philosophy “don't work hard, work smart,” and studying them will give us a deeper understanding of the underlying mathematical subtleties of DSP. In this chapter, we present a collection of these tricks of the trade, in no particular order, and explore several of them in detail because doing so reinforces the lessons we've learned in previous chapters.
