利用FPGA实现的脉宽测试技术,基于VHDL,测试误差为时钟周期

说明：  本光盘是《数字信号处理FPGA实现》一书的配书光盘，内容包括了书中第二章给出的所有示例以及该书的12个实验完整的工程文件。 本光盘根目录下有3个文件夹，分别为dsp48_application,dsp48e_application和DSP_Example。(This CD-ROM is the CD-ROM of the book "FPGA implementation of digital signal processing". It includes all the examples given in Chapter 2 and the complete engineering documents of 12 experiments in the book. There are three folders in the root directory of this CD-ROM, which are dsp48_ application,dsp48e_ Application and DSP_ Example.)
