DEFINITION

Classification: 365/189.01

READ/WRITE CIRCUIT:

(under the class definition) Subject matter for inserting, extracting, or handling of an information signal to be stored or retrieved.

(1)

Note In this and its indented subclasses the term "processing" as applied to signals is specifically intended to excludedigital data processing systems and computer systems
