Maybe DSP is not dead but has just left the building, moving into new and more profitable areas?
Will would be the first to point out, as he does expertly every month in his newsletter, that DSPs are all over the place (mainly in cellular handsets), but are hidden from the view of all but a few programmers. However, old DSPing techniques are constantly being re-discovered in new areas (see the article on faster than Nyquist in this news feed for example) in many cases as a result of the overall advancement of technology. Big Data, Cloud Computing and the Internet of Things (IoT), in particular have expanded the application reach of DSPing concepts, introducing them to a broader group of innovative people. IoT may even lead to a resurgence in DSPors. Neural networking for instance, just fancy adaptive filtering, used to be solidly in the DSPing camp but is now a sexy big data technology and is often introduced as a new technology. Classical DSP was based on models from Physics but Machine Learning is based on models from data and hence Digital Signal Processing engineers have morphed into Data Scientists. DSPing remains on the front end of all of this for the pre-processing of signals into data. As we said above, the end of Moore and Denning may bring back DSPor type systems with a vengeance in the next few years, maybe specifically for deep learning. |
