Acceptable values for filter bandwidth and amplifier output power are determined by means of numerical simulations under the criteria of tolerable maximum standard deviation of timing jitters and… (More)

The cost and the reliability of a transoceanic link depend widely on the number of line repeaters. The concept of inline remote pumping can be an interesting new solution to reduce its number. To… (More)

filter output node and the other constitutes the additional observation point. Obviously, this point has to be judiciously chosen to be able to obtain an increase in fault coverage. So, the two… (More)

Diffraction effects are important in many acoustic surface wave (a.s. w) devices : delay lines, acoustic lenses, apodized filters, helical long delay lines... If the slowness curve (i.e dependance of… (More)
