Introduction
I’ve compiled a list of DSP wisdom I have learned and used over my career. The list is a collection of aphorisms in the vein of Nassim Taleb’s Bed of Procrustes, Epictetus’ Handbook and Proverbs. This blog post will be updated over time and used as a reference in other posts.
Aphorisms
- If you need to do something in DSP it’s best to do it with a filter
- Odd-lengths are preferable to even-lengths in an FIR filter.
- From @lambdaprog on Twitter: “I just had to coin this “SDR Wisdom” for a customer today. Maybe it can help: High Performance, Wide-band Coverage, Low Cost. Chose two.”
