A DELTA-SIGMA MODULATION SYSTEM FOR TIME DELAY AND ANALOG ,UNCTION STORAGE,

Abstract

Modified delta modulation (delta sigma modulation) permits magnetostrictive delay line function storage of analog data with the significant advantages of pulse regeneration with clock gated logic and relatively inexpensive conversion equipment. Five to 10 msec delay lines with a 2 mc bit-rate accommodate analog signals of up to 8 kc with phase shift below 2 degrees; total dynamic error is within 0.2 % of half scale up to 1 kc. An adaptive filter permits a further trade off of accuracy for bandwidth during computation. This paper describes the design of the delta-sigma modulation systems and presents test results. (Author)
