Integrator design for a differential analyser

The paper sets out to examine various integration algorithms, suitable for implementation in the form of serial binary arithmetic, and concludes that only first-order integration is practicable at the present time and that only first-order prediction is necessary or desirable. An examination is made of the errors inherent in digitizing the main functions of the traditional analogue computer (integration, multiplication, division) and some conclusions reached about the feasibility of building a digital differential analyser given the current state of technology.
