Arithmetic circuitry for a time-sequential pulse-position-modulation analog computer.

University of British Columbia

This thesis is concerned with the arithmetic circuitry of a time-sequential pulse-position-modulation analog computer. The principal feature of this computer is that functions are represented as pulse positions which occur in time-sequence. Arithmetic circuitry is developed which can manipulate functions in this form on a time-sharing basis. For simplicity in design, the essential arithmetic operations, addition, subtraction, and multiplication, are performed by the various arrangements of three basic units - an integrator, an "on-off type" gate, and a voltage comparator. The remaining aritmetic operation, division, calls for additional units. Input-output operations and function generation utilizing these basic units are also described.
