Simplified Methods for Computing Performance of Transmitting Tubes

Simplified methods are given for quickly computing with reasonable accuracy the performance of transmitting tubes in the usual radio-frequency and audio-frequency applications. These applications cover the cases where the current wave shapes within the tube are pulses of current which flow for less than the full cycle. The factors controlling the shape of these pulses are discussed and a simplified analysis of the pulses is presented. The problems of choosing the optimum conditions for a transmitting tube are discussed and the conditions for fully utilizing a tube´s capabilities in the different classes of service are presented. These methods are illustrated thoroughly by calculations for a standard transmitting tube.
