ABSTRACT:
A system for high speed acquisition and storage of data from transient electrical signal waveforms sampled in time at a multiplicity of points, and where it is desired to collect and store data in real time in a mass storage unit, but where the data rate is in excess of the apparent rate at which data can be transferred to mass storage. The overall system employs two levels of data reduction, the first being digital integration (summation) and the second being data processing. In the digital summation section memory read and write cycles overlap for higher speed. In one embodiment, a charge-coupled device is employed as an input element to reduce the data rate prior to subsequent digital processing. The system is capable of recording all the intensities of all transients continuously without loss of data significance.
