Based on time amplification and coarse time measurement technology,a novel jitter measurement system implemented by FPGA and PCI Express bus was introduced and has merits such as simple structure,high precision,flexible and low cost design with the help of time amplifier.

In this thesis, we consider the nonlinear impulsive dynamic system on time scales.

Finally, we introduce the development of theory of time scales which unify continuous and discrete analysis.

It is composed of two chapters, which respectively study oscillation solutions of a class of nonlinear delay dynamic equations on time scales and the existence of unbounded positive solutions of certain delay partial.

By using the Mawhin coincidence degree theory,we discuss the existence of solutions to the periodic value problems to the nonlinear dynamic equations on a class of time scales and obtain some results and show an example.

In this paper,the nonoscillation for a delay dynamic differential equation are studied on time scales and some properties of nonoscillatory solution are obtained.

In this paper,we study the distance evaluation of zeros of solution of first order delay differential equation on time scales and obtain some theorems.
