So if I measure the null-to-null spacing in the S11 plot from a non-50 ohm transmission line and then calculate the delay using your formula given earlier: delta f in GHz) = 1/(2*Td) is Td also the group delay? Will a non-consistent group delay issue show up as variation in the measured S11 null-to-null spacing?
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.
