Abstract:

A Pulsed Analog Computer has time-shared analog computing elements. Previously, a family of highspeed pulsed analog computing elements operational amplifier, decoder, sample and storage gates, etc. capable of operation in 10 micro sec was developed. Tests of these elements are described under the control of a program stored in the memory of a general purpose digital computer, the TX-O. The combined system, which includes a sequential digital machine to assist in the interpretation of this stored program and the transfer of data between the analog and digital domains, is called the Pulsed Analog and Digital Computer PADIC. Sequential analog operations can be performed at a rate of 80,000 per second, with accuracies approaching 1. The design procedures can be used for construction of larger systems for any purpose. As a test problem, the generation of an arbitrary function of a single variable stored as discrete points in the digital memory was accomplished using the experimental PADIC system and compared with the digital solution. Each pulsed-analog function interpolation was completed in 162 micro sec including memory accesses and this time can easily be reduced. 9author
