The Measurement of Radio Frequency Resistance, Phase Difference, and Decrement

Abstract

Various methods of measuring radio (high) frequency resistances, the power factor or phase difference of radio condensers, the sharpness of a resonance curve, and the decrement of a wave have been given. It is proposed in this paper: (1) to show that these quantities all express essentially the same physical magnitude and hence a single process of measurement gives them all; (2) to derive and classify the methods of measurement; (3) to describe improvements in these measurements. RELATIONS OF THE QUANTITIES The principal difference between the phenomena of radio (high) and audio (low) frequency is the importance of capacity,,
