Item Description

Variable Frequency Electric Circuit Theory, development of a variable frequency electric circuit theory with application to the theory of frequency modulation. Bell Telephone System, Monograph B-1032

'In this paper the fundamental formulas of variable frequency electric circuit theory are first developed. These are then applied to a study of the transmission, reception and detection of frequency modulated waves. A comparison with amplitude modulation is made and quantitative formulas are developed for comparing the noise-to-signal power ratio in the two modes of modulation'(from the Abstract)
