Class Information
Number: 330/117
Name: Amplifiers > With unbalanced-to-balanced coupling
Description: Subject matter including in the signal path a circuit electrically unbalanced to ground, or a convenient electrical reference potential plane, from a single source of electrical signal and having at some subsequent location of the signal path, with or without one or more intervening amplifying devices, a balanced circuit wherein at least two of the conductors have at any instant electrical signal flowing therethrough substantially equal and opposite in sign with reference to ground or some other convenient reference plane.
