探讨了对高频信号进行采集和处理的设计难点，提出将LabVIEW的采集数据的特性与MATLAB强大的计算能力相结合的方法，并以此设计了一个系统。然后通过3种不同的方法，分别是将txt文件引入MATLAB、使用MATLAB script、使用Math Script RT，来结合LabVIEW和MATLAB，以采集得到的信号和内部产生信号的均方差及相关系数为标度来分析不同方法的可行性及效率，通过对比结果，最终确定了一种最佳的方案。

This example program shows how to configure and use the A/D Converter of the following microcontroller: STMicroelectronics ST10F166 After configuring the A/D, the program reads the A/D result and outputs the converted value using the serial port. To run this program... Build the project (Project Menu, Build Target) Start the debugger (Debug Menu, Start/Stop Debug Session) View the Serial Window (View Menu, Serial Window #1) View the A/D converter peripheral (Peripheral Menu, A/D Converter) Run the program (Debug Menu, Go) A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change. Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µ Vision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.

The tar file contains the following files: ptfsf.c: heart of the perfect TFSF code ptfsf.h: header file for same ptfsf-demo.c: FDTD code which demonstrates use of perfect TFSF code. Essentially this program used to generate results shown in the paper ptfsf-file-maker.c: code to generate an incident-field file using the "perfect" incident fields ptfsf-demo-file.c: FDTD code which uses the perfect incident fields stored in a file fdtdgen.h: defines macros used in much of my code Makefile: simple make-file to compile programs Also include are some simple script files to run the programs with reasonable values. The code assumes a two-dimensional computational domain with TMz polarization (i.e., non-zero field Ez, Hx, and Hy). The program is currently written so that the incident field always strikes the lower-left corner of the total-field region first. (If you want a different corner, that should be a fairly simple tweak to the code, but for now you ll have to make that tweak yourself.)
