All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Many voltage regulators are of the fixed output variety and include the voltage divider internal to the regulator. There are definite advantages to this approach, which allows active voltage trimming ...

Classic techniques like videofluoroscopy, stationary manometry, and ambulatory 24 h pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and reflux-related symptoms.

Today’s electronic equipment must be designed to, first, operate in the electromagnetic (EM) environment it is to be employed in, and second, ensure that the EM fields generated by the system do not ...

Depending on the earthing configuration of the network, the instrument also uses multiphase measurements to calculate the impedance of the neutral conductor, enabling it to reveal defects that could ...

We’ll begin by covering some of the basic mathematical relationships that everyone learns in electrical trade (or engineering) school. Unfortunately, many people seem to forget these basics in the ...

Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...

Achieving Gigabit data rates is a challenge that can excite the imagination of chip designers. An equally significant challenge is making these designs testable, but somehow designers don't get ...
