varying any of the applied voltages. Another conditionfor equation (4) is that the grid should not become sufficientlypositive to distort the characteristic. Under these conditions Ihave generally found this equation to hold sufficiently well, to afirst approximation at least, and have been using… … 15 ZO 25 Grid Volts Fig. 75. Latour ^ has derived some equations for the relay effect of audion tubes. He starts from the general functional expressionsfor the plate and grid currents: If^F{Ep, Eg) and Ig=f{Eg, Ep).In the expansion of these equations he neglects all quantities ofthe second and…
