A Method for Rapid Analog to Digital Conversion.

Abstract

A method has been developed for rapid analog to digital conversion of data using a PDP-8 (Lab 8/E) computer and an industry-compatible digital tape recorder (TM8-EA). The analog data are transducer signals from a sled test event, lasting about 500 msec. Up to 16 channels of these data can be digitized using two 8-channel multiplexers and a 10 bit A/D converter. The frequency content of the signals requires the sampling rate to be at least 2000/sec/channel. By using 2 buffers concept, a maximum conversion rate of 26,000 words/sec can be achieved without loss of data.
