Oscillations in the Circuit of a Strongly Damped Triode

The following is a study of the particular action produced by a triode oscillator when the relation of the inductance to the capacity, L/C, is greater than the square of the interval resistance, ρ², and when the reactive coupling between plate and grid is greater than the limit required for starting oscillation. The shape of the oscillation curve is clearly other than sinusoidal, the frequency is much lower than that usual in the LC circuit, and is determined essentially from the constants of the triode and from the current.
