The smallest increment in distance that can be distinguished and acted upon by an automatic control system.

In radar, the minimum separation between two targets, in angle or range, at which they can be distinguished on a radar screen. Also known as resolving power.

In television, the maximum number of lines that can be discerned on the screen at a distance equal to tube height; this ranges from 350 to 400 for most receivers.

For a vector, the determination of vectors parallel to specified (usually perpendicular) axes such that their sum equals the given vector.

The process of separating a racemic mixture into the two component optical isomers.

1. For a measurement of energy or momentum of a collection of particles, the difference between the highest and lowest energies at which the response of an instrument to a beam of monoenergetic particles is at least half its maximum value, divided by the energy of the particles.

2. The procedure of breaking up a vectorial quantity into its components.
