Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. The L-network is a real workhorse impedance-matching circuit (see “Back to Basics: Impedance Matching (Part 2)” ) ...

Photocouplers optically links, via transparent isolating material, a light emitter and a photodetector. Used as an interface between circuits with different ground potentials, photocouplers replace ...

This paper describes the method used to design the basic control algorithm of a lane-keeping support system that is intended to assist the driver's steering action. Lane-keeping control has been ...

Even if you're not ready to take the plunge into fire alarm system design and installation just yet, you should still know the fundamentals in order to perform emergency work. This includes knowing ...

Extension of phase-shedding techniques commonly used in intermidiate-bus architecture to Vicor's current-transformer approach. Fig 1. Designers can parallel identical fixed-ratio isolated bus ...
