Mark Maddox @ edn.com has a design idea on cold-junction compensation using AD7708. The accuracy of any circuit or system that uses a thermocouple to determine the temperature of a process is limited by the accuracy of the method used to perform cold-junction compensation. In a thermocouple measurement, two wires of dissimilar metal join together […]

Compensation of Oscilloscope Probes

by Maurizio @ dev.emcelettronica.com: Using simple wires to measure signals with the oscilloscope would result in unreadable plots on the scope, the main reason being the noise coupled onto the “probe” itself. The first line of defense against that would be to use a coaxial cable as a probe, which would prevent external noise coupling. An unwanted […]
