DEFINITION

Classification: 333/18

(under subclass 17) Systems and networks provided with automatically operated means to control an equalizer and delay network.

(1) Note. This subclass includes systems including an equalizer and/or a delay network which is automatically controlled in response to some condition in the system and also equalizers and/or delay networks which are provided with other automatic control means.
