DEFINITION

Classification: 505/863

Stable state circuit for signal shaping, converting, or generating: (Class 307/277):

(under subclass 857) Subject matter including circuit means capable of at least one or more distinct current conductive stable states for, (a) producing an output signal having a particular waveform; or (b) modifying either, (1) a constant (DC) input, or (2) the waveform of a time varying (AC) input signal.

(1) Note. The modified form or shape is not merely one of magnitude such as would result from a change in amplitude or frequency, but is the result of the modification or conversion of one waveform into a waveform of significantly different form a shape.
