@sheepdoll--To your point"Regarding the demise of analog engineering. It seems that analog circuits like the example posted are easy to solve with field equations in a simulator (Ironically digitally implemented.) Are we too dependent on such tools such as Matlab, and pSpice which can add to the cost of the project?"
Expertise in analog layout and design is still the key to a good analog designer. My analogy of a doctor: you go to medical school and learn it all and then you specialize----engineers need to do that better than we do now and continue to learn always
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.
