21. I think I'd had the new AMS delay line for about two weeks. 22. Delay line interferometers are also known as optical DPSK demodulators.23. Main memory was random access delay lines provided temporary storage. 24. A later version of the delay line used metal wires as the storage medium. 25. It is possible to cascade a delay line with another type of all-pass filter. 26. An optical delay line is used to vary the timing of the detection pulse. 27. The probe is directed into an optical delay line . 28. Other types of delay line include acoustic ( usually magnetostrictive, and surface acoustic wave devices. 29. In 1944, Madison G . Nicholson applied for a general patent on magnetostrictive delay lines . 30. The diffracted light is focused onto a 170x10 mm cross delay line microchannel plate detector.
