In reviewing these articles, it appears that the only real advantage of this technology is hardware footprint, but it still works analyzes signals serially except now the issue is noise and distortion comes into play. So when is the next technology coming that can take a signal and process it in parallel?
SNR is not useless, but should be properly treated. One of good measures for ADC noise performance is dBFS/Hz, which is power ratio of full-scale harmonic signal to noise density. Consider this article (sorry not in english), but pictures and equations are clear.
Note that this is status quo of 2004 year, nowday ADCs are about 4 dB better:
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
