DEFINITION

Classification: 708/845

Function generation:

(under subclass 801) Subject matter wherein the wave shape of at least one analog signal representing a desired function is generated by mathematical operation or a signal is generated as a part of a mathematical operation representing a desired function of at least one variable input parameter.

(1) Note. This and the indented subclasses include waveform synthesizers of the analog type wherein the waveform is internally generated.

(2) Note. Trigonometric waveform generation is excluded.
