DEFINITION

Classification: 330/100

(under subclass 99) Subject matter wherein at least one of the signal feedback means has the signal feedback applied to the signal input of a prior stage so that the path of such feedback means extends to include all or a portion of at least one other signal feedback means (overlapping

feedbacks).
