    The theory of operation of the three-electrode thermionic vacuum tube given in this paper is based on the fundamental equation of the family of characteristic curves for various plate and grid voltages. This equation, which may be written I= a( R_ EB + 2; E,+ C) where E<L>b</L> and E<L>c</L>, are the plate and grid voltages respectively, and α, μ<L>0</L&g... View full abstract»

    In a first addendum, the author shows a later method of measuring directly the mutual conductance of tubes, which method is free from certain possible objections of the earlier procedure. In a second addendum, an autodyne oscillator with inductive coupling between grid and plate circuits is analytically considered. The condition for sustained oscillation is derived, a numerical illustration given,... View full abstract»

    Starting with a functional relation between the plate current and the grid and plate voltages, the plate current variation is deduced to a sufficient degree of approximation in terms of constants of the tube and the grid voltage variation (for pure resistance in the output circuit). The requirements of amplification, modulation, and detection are then deduced from the equations obtained. Heterodyn... View full abstract»
