DEFINITION

Classification: 327/64

With logic or bistable circuit:

(under subclass 63) Subject matter wherein the comparison by amplitude (a) includes a device performing Boolean functions such as AND, OR, or exclusive-OR or (b) utilizes a device having two stable states.

(1) Note. The combination of logic with specific amplitude comparison circuitry or function, not elsewhere classified is classified here.
