Computer-aided Instructional System for Transmission Line Simulation.
Reinhard, Erwin A.; Roth, Charles H., Jr.
A computer-aided instructional system has been developed which utilizes dynamic computer-controlled graphic displays and which requires student interaction with a computer simulation in an instructional mode. A numerical scheme has been developed for digital simulation of a uniform, distortionless transmission line with resistive terminations and arbitrary voltage sources at either or both ends of the line. The numerical transient and steady-state solution is independent of the number of spatial increments used to simulate the transmission line. The numerical solution provides data for an on-line CRT display unit which permits visual observation of the space-time dynamic behavior of the voltage and current waves. A computer-controlled audio tape recorder, a special keyboard, and special software for dynamic scope displays and for lesson programing have been developed as part of the instructional system. This system permits student interactions with a computer programed lesson and associated laboratory stimulations to create learning experiences which cannot be duplicated in the classroom or laboratory.
