01 July 1939
Frequency-Modulation: Theory of the Feedback Receiving Circuit By JOHN R. CARSON T H I S paper m a y be regarded both as a continuation of a prior one by the writer and Thornton C. Fry ] 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 1 is absolutely necessary, since the fundamental analysis and the formulas there developed are too lengthy.to be repeated here.
