A theory of determining the dynamic sensitivity of cathode–ray tubes at very high frequencies by means of Fourier transforms

Fourier transforms have been used in a theory of determining the dynamic sensitivity of cathode-ray tubes at very high frequencies. The exposition of the theory is facilitated by means of analogous conditions in the theory of inhomogeneous transmission lines recently presented. Thus, for instance, the simplest case with parallel plates neglecting stray fields and exit displacement is analogous to the exponential line. The method of determining the dynamic sensitivity of a cathode-ray tube having various forms of its plates is presented. Finally the problem of constructing a cathode-ray tube having an optimized sensitivity curve is discussed.
