(under the class definition) Subject matter which includes devices for performing calculation operations upon electrical signals, such as current or voltage, which are continuously varying representations of physical quantities and which are some function of the quantities such as direct proportion,

inverse proportion or square law relationship.

(1) Note. The limited logic operations include comparison or selection, for example.

(2) Note. The continuously varying representations, for example, may be frequency or pulse width.

(3) Note. Signals wherein the varying representation is pulse rate are included with subject matter under Electric Digital Calculating Computer".

(4) Note. Examples of the physical quantities above are temperature, pressure, angular position, or weight numerical values.
