Abstract
The following paper describes and analyzes mathematically a new principle in amplifier design. It is shown how noise, phase shift, frequency distortion, etc., can be largely eliminated by use of the "balanced feed-back principle" without reduction of the over-all gain of the amplifier. By means of balanced feedback the linear range of an amplifier using ordinary receiving-type tubes has been extended from an upper limit of 600,000 up to 2,500,000 cycles. Theoretical and experimental results were found to check closely.
