Pressure mounting for tantalum capacitor price hike News & Analysis 1/28/2002 Post a comment Tantalum powder suppliers are denying requests by several major capacitor makers to renegotiate multiyear "take or pay" contracts signed at the height of the last component shortage, putting severe pressure on their already depressed margins.
Kemet reports loss after restructuring charge News & Analysis 1/22/2002 Post a comment
Despite signs of an uptick, Kemet Electronics Corp. reported a net loss of $26.9 million or 31 cents per diluted share in its third fiscal 2002 quarter ended December 31, 2001, after a $38.5 million pretax restructuring charge to streamline manufacturing facilities, accelerate productivity improvement programs, and reduce its workforce by another 1,600 employees.
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.
Passive component makers slashing capex again News & Analysis 1/8/2002 Post a comment Passive component vendors are keeping the lid on capital expenditures this year as inventory and capacity utilization rates remain at undesirable levels.
Unable to justify equipment purchases, many passives companies are sharply scaling back budgets for the second consecutive year. In 2000, companies invested heavily in additional plants to fill shortages of many commodity parts.
Drones are, in essence, flying autonomous vehicles. Pros & 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? Is the technology advancing faster than we can answer the questions it poses?
