The best-performing, highest-quality, and likely also most expensive differential link you will ever encounter appears on the front panel of an Agilent differential-network analyzer. This ...

The need for conditioning low-level ac signals in the presence of both common-mode noise and differential dc voltage prevails in many applications. In such situations, ac-coupling to instrumentation ...

One type of coupling has small metal roller bearings, and clamps at one or both ends. A second, plane bearing couplings, has a clamp on one end. For general information about the UCLA differential ...

Each of these components consists of a series of circular metal discs lined on 4 cm. shaft with couplings on one end. One disc is cross-hatched on the edge. The number of discs on a shaft varies. For ...
