Foreword:
When I was in the signal and system course, for the convenience of electronic notes, learned a little bit about the use of latex to hit some formula of signal and system, such as Fourier Transform and so on, a lot of wrong place please correct me,
a, software installation:
1. ctex:http://www.ctex.org/ctexdownload
2. MathType: https://www.mathtype.cn/xiazai.html (note: personal installed licensed, only 30 days, if you need to use for a long time, to crack,)
2, software learning:

3, software use
the basic use latex has mentioned in the tutorial, I'm going to share my some skills in the process of using,
1. The use of MathType
When we meet with some not dozen of symbols, usually how baidu search this symbol in latex said, but don't even know how to read this sign, we can want in MathType mathematical input panel handwritten input expression of symbols, the symbol will be displayed in the MathType, so by copy and paste can be pasted into latex,
1.1 configuration MathType copying and pasting properties
MathType to preset, cut and copy the preset - MathML drop-down choice latex2.09 - sure
1.2 using MathType
MathType to edit -> open mathematics input panel, use the mouse to draw characters - found in panel want characters, click the Insert -> copy of MathType characters - glue to Latex,
2. CTEX (mainly Winedt) using
2.1 code to simplify
1. Sometimes we often need to input the same code, but the code is too long, use custom code will save a lot of time,
Example: the semicolon code \ frac simplified \ fc,
\ newcommand {\ fc} {\ frac} 
(2) sometimes for a great mathematical formula, mathematical formulas are used globally uniform font,
Example: a mathematical formula global displaystyle
\ everymath {\ displaystyle} 
remember: 99% latex problems can find the answer in baidu,
