摘要脉冲信号发生器是信号发生器的一种，可以产生重复频率、脉冲宽度及幅度均为可调的脉冲信号。随着电子技术的迅速发展，高速脉冲信号发生器已经广泛应用于通讯、测控、电子对抗、激光技术以及现代化仪器仪表等各种电子系统的测试和精确控制中。同时，脉冲信号发生器是雷达应用产生时序和控制信号的核心部分，可以通过改变雷达的不同相位实现侦查、追踪和获取目标。
本设计在分析了脉冲信号发生器的特点后，采用Altera公司的QuartusII开发软件，对CycloneII系列的EP2C35F672C6芯片进行开发，在DE2板子上通过晶振电路产生基本脉冲，利用FPGA设计并实现分频、脉宽调节和单个脉冲输出等基本控制，并可通过串口输入控制和LCD显示，从而实现一个可以进行频率和脉宽调节控制的脉冲信号发生器。9516

Title FPGA-based Design and Implementation of Pulse Signal Generator
Abstract
The pulse signal generator is a kind of signal generator, which can produce pulses with adjustable frequency, pulse width and amplitude. With the rapid development of electronic technology, high speed pulse signal generator has been widely used in communication, monitoring and control, ECM, laser technology, modern instruments and other electronic system of testing and precise controling. At the same time, the pulse signal generator is the core part of producing timing and control signals in radar applications, by changing the different phase of radar to realize the goal of investigation, tracking, and getting targets.
After the analysis of the characteristics of the pulse signal generator,the design used the QuartusII development software by the Altera company, on CycloneII series of EP2C35F672C6 chips for development in DE2 board. Through the basic pulse generated by crystals circuitry, we used the FPGA to realize the frequency demultiplication, pulse width adjustment, the single pulse and other basic controls, and through a serial port input control and LCD display to achieve a signal pulse generator with undertake frequency and pulse width adjustment.
