有没有知道扫频信号软件原理的

lv的help->chirp pattern:
Chirp Pattern Details
If the sequence Y represents Chirp Pattern, the Chirp Pattern VI obtains the elements of Y using the following equation:
yi = A*sin((0.5*a*i + b)*i)
for i = 0, 1, 2, …, n – 1
where A is amplitude,
a = 2(f2 – f1)/n,
b = 2f1,
f1 is the beginning frequency in normalized units of cycles/sample,
f2 is the ending frequency in normalized units of cycles/sample,
n is the number of samples.

看matlab帮助文档里面的说明，搜chirp或者sweep
有分段扫频、线性扫频、对数扫频等等多种扫频信号
