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
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
