Laplace Transform Flashcards
1
Q
What is the purpose of Laplace Transform
A
-transforms an LTI from time domain to frequency domain
-allows us to solve differential equations (frequency response)
2
Q
Define a transfer function
A
The ratio of Y(s)/U(s) = G(s)
3
Q
Define a characteristic equation
A
setting the denominator polynomial to 0
4
Q
What is forced response?
A
the way a system responds to changes in the forcing input
5
Q
What is a natural response?
A
depends only on the system and initial conditions
