Two popular ways of measuring the loop gain T of a negative-feedback circuit are Middlebrook’s double-injection method [1] and Rosenstark’s open-circuit/short ...
Editor’s note: This month we are pleased to have Colin Wells from Texas Instruments as our blogger. In modern industrial control systems, 4-20 mA current-loop transmitters remain one of the most ...
Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...
Observations on nodal and loop analysis that can save a fair amount of scribbling of equations when using Kirchhoff's laws. In a previous Idea for Design, Anshi Chen outlined a method for analyzing ...
