Abstract
An imperfectly filtered d.c. operating voltage is applied to an electrode, such as the emitter electrode of an output transistor, an input signal being applied to another electrode, such as the base electrode of the transistor. The ripple component thereby induced at the collector electrode of this transistor is cancelled by adjusting to a value exactly equal thereto, the complementary ripple component of the d.c. operating voltage applied to the collector electrode.
