TITLE: What is the difference between an impulse response and a transferfunction?
QUESTION [5 upvotes]: An imupulse response, is the output you get when you apply an impulse, like a delta dirac function, to your system (only for LTI?).
By knowing the impulse response you know the system.
The transferfunction relates the input to the output. I.e. this is a representation of the system.
So aren't both the same? Or Did I misunderstand something?

REPLY [4 votes]: Impulse response represent the system in time domain and transfer function represent the system in frequency domain. Essentially both are same.
