This thesis discusses an analogue method of function generation using a magnetic drum. The function generator is suitable for use in a pulse- position-modulation analogue computer which operates on a time-sequential principle and in real time. The functions are approximated by linear and parabolic arcs, and the break points are represented by pulse posit ions. These pulse positions are stored on a magnetic drum. The function generator converts these pulse positions into the original function by using precise sweep amplifiers and gating circuits. The number of functions that are available is limited only by the size of the drum. The method of function generation proposed here allows for very simple programming of the computer. Accuracies approaching one per cent were obtained in tests using very inadequate sweep amplifiers. Accuracies of the order of one-tenth of one per cent are believed to be possible by using the proposed function generator that is described at the end of this thesis. This thesis also describes the synchronization and counting circuits that are required to control the operation of the computer. Also the circuits required to write the information pulses on the drum are described. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

The combinations of analog and digital equipment to form hybrid installations are of such variety that hybrid software routines are generally restricted to particular hardware configurations. The software developed in this thesis is applicable and operational on the EAI PACE-231R-V; DEC PDP-9 Hybrid Computer. The programs (in the form of subroutines and handlers) are structured, according to the characteristics of this computer, to handle the general situations of hybrid programming; such situations as the synchronization of the analog and digital computers, and the transfer of data and control information. The present level of software development has considerably simplified the use of the interface for hybrid problem applications. Successive stages of software development would incorporate this stage, in whole or in part; each stage being more comprehensive and sophisticated than its predecessor. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
