There are still systems that are almost completely analog -- like audio amplifiers -- also I guess there are still analog filters and signal conditioning circuits -- but the vast amount of signal processing is now performed in the digital domain (DSP) and there is relatively little analog signal processing (ASP) these days
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
