Abstract

898,778. Digital integrators. ROE & CO. Ltd., A. V. Aug. 27, 1959 [Sept. 1, 1958]. No. 27952/58. Class 106(1). The digital integrator of Specification 886,382 is modified by providing that one of the serial registers is replaced by a pulse counter. As shown, pulse counter j accumulates dy to form y. The contents of j are dynamicized continuously by k and fed in serial form to the gate h opened by dx inputs and are then added in g to the contents of serial register f to form d2. Pulse counter j may be constructed as disclosed in Specification 880,014 and register f as in Specification 883,757. The gate h may be omitted and the dynamicizer operated by dx inputs.
