DEFINITION

Classification: 330/91

(under subclass 90) Subject matter wherein the diverse signal feedback is derived from the cathode feedback impedance and fed to the input electrode of the same or a prior stage; or wherein the diverse signal feedback is derived from an output electrode of the same or a following stage and applied to the cathode impedance.
