Abstract:

Digital differential analyzers are a new type of analog computer, distinguished by increased potential accuracy over other analog machines. Most recent models of DDA have integrator registers containing 6 to 8 decimal digits, which makes it possible to obtain solutions with 5 to 6 true decimal places. This is 2 to 3 orders of magnitude greater than the accuracy of other types of analog machines. The solution of the problem of the speed of operation of DDA requires a specific approach. As noted, as a result of each individual iteration, the value of any variable represented by delta modulation of a pulse voltage, including the variable used as the solution of the problem, can vary only by the magnitude of an elemental increment.
