Test instrument delivers pulse and noise generation Product News 1/30/2008 Post a comment Agilent Technologies claims to introduce the industry's first pulse function arbitrary noise generator, which is said to provide superior signal quality combined with versatile waveforms for general-purpose bench tests or advanced serial data stress tests.
Measuring HD performance with Tektronix' Picture Quality Analyser and other tools Design How-To 1/25/2008 Post a comment While the quality of analog and full-bandwidth digital video can be characterised indirectly by measuring the distortions of static test signals, compressed television systems pose a far more difficult challenge. Picture quality in a compressed system can change dynamically based on a combination of data rate, picture complexity, and the encoding algorithm employed.
Optical analyzers extend reach Design How-To 1/21/2008 Post a comment No radio engineer would think of doing without a spectrum analyzer, but developers working in the electromagnetic spectrum's optical range have had little choice.
Measuring video quality: Can objective metrics match human eyes? Design How-To 1/4/2008 Post a comment Can objective metrics replace the "gifted" human eye when evaluating video quality? In short -- no -- but they have an important purpose. Subjective video analysis is costly, time consuming, and difficult to repeat. Objective metrics act as important evidence, while subjective analysis provides the confirmation.
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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
