Second-order IIR Filters will support cascade implementations - 5 Part digital audio application tutorial Design How-To 7/1/2003 3 comments It is possible to implement IIR filters of any order by cascading first- and second-order IIR sections. Today, as digital audio processors embodying this topology becomes commonplace in the market, the designer's challenge is to find a way to design coefficients for these to accomplish the overall filtering goal. This multi-part article series - by the knowledgeable and prolific Rusty Allred - brings together the basic information needed to design and implement a wide variety of audio filters. P
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.
