I'm looking for a good Windows based audio spectrum analysis software. I need graphical frequency spectrum plots, amplitudes, also looking for min response levels versus noise. I am evaluating MEMs microphones, looking at various voice and signal input , I want to see frequenecy spectrum output to understand how high and low pass filters should be designed for the circuits next step. Any suggestions? Not looking for free, will pay for reasonable SW value. Thank you.
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.
