Fourier series & Transform
- f(x) satisfied dirichlet Condition
- f(x) must be periodic, with fundamental period
Q: Can we find F.S, for
- introduction of F.T.
- Laplace transform (other integral transform
Q: What happens to the above formula when
The above formula is from the Fourier inversion theorem 逆傅立叶变换
- F.T. of
Find the F.T. of f(t)
Def: The Dirac
function can be loosely thought of as a function on the real line which is zero everywhere except at the origin, which is infinite.
and is also constrained to satisfy the identity:
