- and as we push the boundaries to produce more and more cheaply-made digital logic-driven devices and wireless gadgetry we are adding to the background noise at a fantastic rate, 10dB every few years.
Thresholds are falling, noise rising, we are going to run out of SNR real soon and no amount of diversity, eye diagrams and microvoltmeters will help.
Finally we are going to have to pay attention to shielding, EMI design, precision filters and regulatory compliance just to get the simplest thing to work in this Tempest of our own making.
Only then, maybe, the unintended emitted noise will start to fall, and the power necessary to transmit useful signals will reduce, and a virtuous circle will be created to get us to where we should have been in the first place.
Funny old world, innit?
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.
