Although phase-script logic has obvious drawbacks for present-day computer applications, it is suggested that such logic could be useful for signal processing in connection with phase-shift-keyed data or p.c.m. transmission systems. An example of a regenerative repeater is given which shows significant circuit simplification and possible cost reduction over conventional regenerators. A phase-script logic regenerator realised at a carrier frequency of 4.5 GHz has shown a capability of operating to at least 125 Mbits. Proportionally higher bit rates should be possible with an increase in carrier frequency.
