Abstract
Abstract A data pulse acquisition, storage and read-out system is described which is capable of measuring automatically the amplitude and duration of an input data pulse, and of generating a corresponding output pulse of similar amplitude but of greater duration. A primary function of the system to be described is to translate selected parameters of wide-band, short duration data input pulses, and effectively to reconstitute such pulses into a more suitable format for storage purposes. The stored pulses may subsequently be re-formed by similar circuitry into a facsimile of the original data input pulses.
