19 | DIFFERENTIATING OR INTEGRATING SYSTEMS |

(under the class definition) Passive networks for producing an output wave which is the time derivative or time integral of the input wave.

(1) Note. See the internal and external search notes under subclass 20 of this class for wave shaping systems which may involve differentiating and/or integrating networks.

20, for passive networks for shaping the output wave to other than the time derivative or time integral of the input wave. Also see (1) Note above.
