A Balanced Architecture for Multimedia Sound Design How-To 10/21/1997 Post a comment MIPS are expensive on a host CPU; memory is expensive on a dedicated DSP. Author Jeffrey Barish of EuPhonics discusses the tradeoffs between host processing and DSP processing as well as general purpose vs. fixed function DSPs. While the specifics are sound-based, the principles are generic.
Modulation Schemes: Moving Digital Data With Analog Signals News & Analysis 10/4/1997 Post a comment If modulation makes you sick, don't read Andrew Davis' overview of modulation schemes, and how to stuff a fire hose worth of data down a soda straw pipe. Modulations are in the news these days because they are the subject of many skirmishes in the broadband wars. Both the cable modem vendors and the xDSL vendors are duking it out over modulations and standards. Read why.
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.
