Money Talks by Alex Mendelsohn More Editorials Guest Column. Engineers aren't changing much about the types of measurements they make. But they certainly are changing how they're making their measurements. Notes Oscilloscope designs have used fully differential amplifiers for decades. On Analog System Design Circuit Cellar author George Martin discusses analog systems that contain transducers that represent real-world values such as temperature or oil pressure as voltage, current, or resistance.
Martin lays out a framework for analog system design.
A converters requires a system-oriented approach, says Fujitsu Microelectronics author Paul Maddox. His article helps assess how actual performance departs from the ideal, and why you need to focus on performance parameters such as signal characteristics at various frequencies, or performance reductions for output signals in particular frequency bands. The Dl0 Expert is a fiber optic sensor featuring dual output-channels with independently configurable setpoints that enable it to solve challenging applications, with as little as 1 percent contrast. The Sensing Face Cherry Electrical Products announces its Model MP1021 Series solid-state magnetic proximity sensor line. These Hall-effect sensors are claimed to be the first types that permit you to specify the sensing face.
