Thread: Laplace transform

Hi

I would like to pass to frequece domain the expressions below
if possible with step by step using Laplace transform, because
I not only want the answer, but also learn how to solve them:


7/s(s+30)


1/s^3


3pi/s^2 + 9pi^2

Thanks in advance

Moses

Have you not been taught how to get a frequency response from the Laplace transform representation of a transfer function?

(just replace by )

Thank you for quick reply

Could you please check below and let me now if this is the right results


7/(+30)


1/^3


3pi/^2 + 9pi^2

It is worth simplifying these, (and the last question looks like it has a typo) but they look OK. You might want to turn them into amplitude and phase form.

Please let me know if simplification below is correct and whether
or not I can simplify beyond it:


7/(+30)
7/(^2+30)


1/^3
1/^3


3pi/^2 + 9pi^2
pi/^2 + 3pi^2
