ABSTRACT:
An information processing system includes a digital computing system, an analog processing device with an arrangement for converting electrical information to information of analog form, and an arrangement responsive to the analog information energy for producing output electrical information. Output data from the digital computing system is applied to the analog processing system via a D/A converter, and an A/D converter applies the output electrical information to the digital computing system. Data modified by the analog processing system may be employed to supplement data applied thereto in a random manner, or in a manner with a known transfer function, in order to introduce perturbations in the data to aid in subsequent processing thereof in the digital computing system.
