DEFINITION

Classification: 327/334

SPECIFIC INPUT TO OUTPUT FUNCTION:

(under the class definition) Subject matter wherein an output is proportional to a nonlinear mathematical expression of an input signal.

(1) Note. Characteristically the input signal is continuous and slowly varying with the output signal usually bearing a mathematical relationship to it.

(2) Note. Boolean algebra functions and linear amplifiers are excluded from this subclass.

(3) Note. The input signals in this subclass do not contain information (data) of any kind. For data processing, see Search Class below.
