测试系统频响函数CAT

Test System for Frequency Function CAT

本文利用了离散傅里叶变换（记为ＤＦＴ）和快速傅里叶变换（记为ＦＦＴ）算法的理论，借助于电子计算机来完成测试系统频响函数的计算机辅助测试（记为ＣＡＴ），并给出测试系统的频谱。

In this paper, the author uses random Fourier convertion function and first Fourier Convertion function theory.With the help of computer,He is successfully obtained and computer-aided measurement for frequency function. The frgquency chart for testing system is also given.
