When selecting an approximate integration technique for use in a digital differential analyzer, such factors as cost, parts count, power dissipation and solution accuracy must be considered. This paper considers the application of the classical rectangular and trapezoidal integration techniques and a new two cycle method of integration, all implemented using commercially available components, in the sine/cosine generator and compares the integration techniques in terms of cost, power dissipation, and accuracy. The two cycle integration technique is shown to have a constructional simplicity near that of rectangular integration and the accuracy of trapezoidal integration.
