Adjustable Digital Time Converter.
Abstract
The presentation covers the analysis, computer solution and simulation, design, construction and performance evaluation of an experimental digital time converter with five compression ratios ranging from 3.16 to 316 in a geometric progression. With an analog to digital converter at the input and a digital to analog converter at the output, this time converter operates with data samples circulating in register rings. The updating of this rotating information occurs at selected slow rates while readout samples are taken at a constant fast rate. The original sequence of input samples is preserved in the compressed output when a correct relationship exists between updating and readout rates, generated in appropriate timing circuits. The compressed signal is presented in segments of approximately .5 second each. The performance evaluation shows that the chosen approach is valid, that an experimental model works as expected, and that subsequent radar systems studies can be made with this time converter.
