DEFINITION

Classification: 323/234

OUTPUT LEVEL RESPONSIVE:

(under the class definition) Subject matter which maintains an output at a desired level through the use of means which responds to deviation in the output level and produces a change in the output which is opposite to the deviation.

(1) Note. Although not specifically included within each of the following definitions, output level responsive systems usually include (a) some means which produces a signal indicative of a condition of the load which is dependent on the output level of the system or the output level of the system itself, (b) some processing circuit which makes use of the signal mentioned above, and (c) a final control device which is controlled by the output of the processing circuit thus producing a controlled output of the system.
