? why you recommend don't use smooth funciton average function
ans: If you use 1kHz IF BW or lower, have a good low noise VNA like ZVA-40 you do not need it, and it masks resonance in systems. Some VNA's store the touchstone with S-parameter smoothing which creates problems. You can post process smooth using Matlab very eaisly. I only smooth group delay btw. Have a plot of this in day 3 I believe.
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.
