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.
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.
