Once the carrier is stripped out, there are going to be two remaining frequencies 10kHz and 15kHz. One represents a binary high and the other the low. I need to monitor the time the signal is either high or low, and I am looking to have .000001s resolution (I may have missed a 0in there).
I am thinking about passing it through a low pass filter, then doing a 64 point FFT with an overlapping moving window. I will then have a threshold that I start a counter once a requency reaches a certain level.
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.
