@aero, I'd have to do the math, but it seems to me that with 2MHz sampling rate you would have two samples to work with to get your desired resolution, and would need to determine the difference between a 10 KhZ and a 15 KHz single with samples a half microsecond apart. I would think they would be indistinguishable without a whole lot of bits of resolution, and any noise would certainly defeat you.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
