Except in very simple or idealised situations, the equations occurring in the study of internal small-signal dynamics of junction transistors defy analytical treatment. This thesis reports the results of the two main non-analytical approaches adopted for tackling this problem (viz.: analogue techniques, numerical methods leading to digital computer programmes). A design theory for the RC-line analogue is developed; it permits the accuracy of the simulation to be determined for a given number of sections. Measurements made on practical analogues designed in this way confirm the theoretical estimates and agree with the corresponding results of the second approach. Parameters characterising the dynamic properties in terms of "charge control" and "distributed perturbations" concepts are derived from numerical solution of the equations involved. Theoretical results are compared with measurement results found in the literature.
