Class Information
Number: 330/116
Name: Amplifiers > With balanced-to-unbalanced coupling
Description: Subject matter including a circuit in the signal path in the conductors of which electrical signal flows so that at any instant the signal potential in the conductors is substantially equal and opposite in sign with reference to ground or some other convenient reference potential plane; and wherein further, in the signal path there is included a circuit in the conductors of which signal flows which is unbalanced to ground comprising a single-sided output load usually of two conductors one of which is at ground or reference potential.
