Frequency-Modulation: Theory of the Feedback Receiving Circuit

Abstract

THIS paper may be regarded both as a continuation of a prior one by the writer and Thornton C. Fry <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</inf> and as a companion of that by J. G. Chaffee 2 the inventor of the circuit under consideration. For an understanding of the present, an acquaintance with the prior paper <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</inf> is absolutely necessary, since the fundamental analysis and the formulas there developed are too lengthy to be repeated here. References to that paper will be designated by (Ref.).
