21. Without digital controls , Xerox officials say it is hard to hold color values during production runs. 22. The digital control electronics of the Voyagers were not based on a microprocessor integrated circuit chip. 23. There is a class of non-digital control mechanisms that can be used to create analog robots. 24. In 1959 Texaco s Port Arthur refinery became the first chemical plant to use digital control . 25. Color monitors have improved greatly, but despite digital controls , they remain analog descendants of Howdy Doody-era ancestors. 26. Izenour also developed such varied technologies as articulated acoustical sub-structures and assorted analogue and digital control systems. 27. From this consideration many errors from classical digital control were identified and solved and new methods were proposed: 28. It is possible in a matrix mixer to combine an all-analog signal path with digital control of level. 29. HLA has also been used to develop the real-time digital control system for TRIGA Reactors by General Atomics. 30. Considering the flow of a digital control system as a basis, a resilient control system framework can be designed.
