Researchers demonstrate that Transformers exhibit linear superposition, where combined inputs from distinct text streams produce outputs that are superpositions of individual next-token distributions. This linearity is intrinsic to the architecture, diminishes during training, but can be restored through fine-tuning, and enables generating two coherent continuations simultaneously from a single forward pass.
This technical article explains how screen current behaves in tetrode RF power amplifiers operating in Class AB1 mode, demonstrating why screen-current meters provide better indication of operating conditions than plate-current meters. Using constant-current characteristic curves for the 4CX300A tetrode, the article analyzes how grid voltage drives plate and screen current variations along the operating line.
