Delay line coherent pulse stacking
Optics Letters, 2016Ultrafast fiber amplifiers are usually limited in terms of pulse energy and peak power due to fiber damage and nonlinearities. On the other hand, fiber amplifiers are very energy efficient. To take advantage of this efficiency, but still scale the pulse energy, coherent combining and pulse stacking have become the method of choice.

Online Service with Delay on a Line
2018In the Online Service with Delay (OSD) problem, introduced recently by Azar et al. (STOC 2017), there are an n-point metric space and a server occupying some point. Points request service over time and these requests need to be eventually served by moving the server to these points.

A delay line discriminator for IFM using a left-handed delay line
Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon), 2010Recent developments in left-handed metamaterials and left-handed transmission lines have led to new approaches to the design of radio frequency components such as branch line couplers. In this paper, the design of a delay line discriminator for instantaneous frequency measurement (IFM) is investigated, where the delay line section is replaced by a ...

Bibliography on magnetostrictive delay lines
IRE Transactions on Electronic Computers, 1961This Bibliography, which has been compiled from many technical publications in this country and abroad, covers a wide area in theory, design, and application. It is of interest to note that the second reference, which discusses the use of a magnetostrictive delay line in an aircraft navigation system, has served as the stimulus for almost all of the ...

Correlation and delay line attenuation
IEEE Transactions on Information Theory, 1959The effect of delay line attenuation on the output of a correlator is studied for the case where the attenuation in db to within a frequency independent loss varies linearly with delay and as the square root of frequency. It is shown how attenuation affects the output signal-noise ratio of the correlator, increasing it for some signal spectrum shapes ...

Ultrasonics, 1965
Abstract Solid ultrasonic delay lines were developed when liquid lines became inadequate: their performance lacked repeatability and their bandwidths and delays were too small. Solid lines are more expensive but offer tight restrictions on performance, particularly bandwidth and delay, and are much less affected by their environment. Because of this,

Delay Analysis of the Distributed RC Line
32nd Design Automation Conference, 1995This paper reviews the step-response of the semi-infinite distributed RC line and focuses mainly on the step-response of a finite-length RC line with a capacitive load termination, which is the most common model for a wire inside the present day integrated CMOS chips. In particular, we obtain the values of some of the common threshold-crossing times at

Delay-Free Asynchronous Circuits with Constrained Line Delays
IEEE Transactions on Computers, 1969Armstrong, Friedman, and Menon have shown how fundamental-mode normal flow tables can be realized without delay elements under the constraint that line delays do not exceed a given chain of gate delays. The state assignments for these tables are designed to yield noncritical races and minimum transition times.

Proceedings of the IRE, 1947
Continuous coaxial transmission lines are described in which the velocity of propagation is about one one-thousandth of the velocity of light. These lines include a solenoidal inner conductor and a Litz-braid outer conductor. Phase and amplitude distortions in such lines are discussed, and design procedures are presented to yield lines of optimum ...

Review of Scientific Instruments, 1974
An optical system is presented that can produce long time delays without long path lengths. This system can also produce pulses of variable length, be used to create various sequences of pulses, and can shape pulses.
