Bandwidth and linearity are each both worthy of their own discussions, but I think that you'll find similar bandwidths of operation for ECMs and MEMS microphones. Many MEMS microphones today have a maximum SPL (clipping point) of about 120 dB. There are certainly ECMs available that are linear to higher SPLs, but again, those are often larger, pro-level devices. I think that we'll start to see more MEMS microphones that are linear to even higher SPLs in the future.
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.
