Certain electromagnetic devices such as differential transformers are effective at translating the displacement of a magnetic armature into an AC voltage, which is a linear function of the ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

DELTA has lifted the application range of variable filters to new levels by introducing a new powerful type of linear variable filter (LVF). Since DELTA offered the first linear variable filters in ...
