Collective Filter Evaluation of an FSD Filter-Based Resampling Algorithm Design How-To 1/15/2002 Post a comment Marek Blok of the Technical University of Gdansk, Poland, presents a collective filter for performance evaluation of a resampling algorithm based on fractional sample delay (FSD) filters. The proposed method is easy to use and lets you compare overall performance of the algorithm based on filters with different impulse response length or design methodology.
Decimation Stages with WDFs for Flexible Digital Receivers Design How-To 1/9/2002 Post a comment Dieter Brckmann of the University of Wuppertal, Germany, describes a decimation filter architecture for highly optimized but flexible digital receivers. By using cascaded low-order wave digital filters for certain blocks, you reduce hardware cost and get superior sensitivity properties with respect to coefficient quantization effects, better noise performance, and less group-delay distortion.
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.
