Experimental Determination of the Fundamental Dynamic Characteristics of a Triode

By picking out the fundamental component only from the distorted current in a triode while functioning, the writer has found first new forms of dynamic characteristics for a triode, which are utilizable for solving various problems not hitherto satisfactorily solved (for example, modulation in radio telephony, the phenomenon of "Ziehen," or "pulling," and so on), and secondly that the grid current may reach a large value and that the factor or constant ν merits attention. Some experiments have been carried out relative to the voltage amplification factor for which a new expression has been found. The work is being continued.
