Abstract

The independence of 2 or more amplifiers corrected to the same organism requires special consideration. Analysis of circuits and empirical tests show that a set of push-pull amplifiers with the first stage of each ungrounded show a satisfactory level of independence (ratio of 0.0015). Standard push-pull amplifiers under the specified conditions show an independence ratio of 0.0075.
