| Abstract: | in some measurement and analysis for engineering, the Laplace transform was considered to be applied in settling the problem of input/output of linear constunt coefficient differential equation. The solutions include transient solution and stable solution. On the other hand, the Fourier transform was considered to be used in settling the problem of transient access. There is not suitable reason to explain it. It is easy to cause readers confusion about Fourier transform. This papor discusses the similarities and differences between Laplace transform and Fourier transform on concept. Their properties are analyzed, and their application example in engineering is presented. |
