Why Do We Use the Inverse Impulse Response in Practical Applications?

Click For Summary

Discussion Overview

The discussion revolves around the concept of inverse impulse response, exploring its significance and practical applications, particularly in the context of systems and signal processing. Participants seek clarity on its usage and examples that illustrate its application.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants inquire about the reasons for using the inverse impulse response and request practical examples to understand its application.
  • One participant explains that the impulse response is derived from stimulating a system with a unit impulse, leading to the output known as the impulse response.
  • Another participant reiterates the relationship between the inverse impulse response and the output of the system, suggesting that it can be represented as 1/h(t) or 1/y(t).
  • There is a repeated request for a clear, practical example of the inverse impulse response in real-world applications, particularly in imaging.
  • A participant suggests using online resources to find examples, providing a link to a paper that may contain relevant information.

Areas of Agreement / Disagreement

Participants generally agree on the basic definition of impulse response and its relationship to system output. However, there is no consensus on specific practical applications or examples of the inverse impulse response, leaving the discussion unresolved in that regard.

Contextual Notes

Participants express uncertainty regarding the practical applications of the inverse impulse response, indicating a need for clearer examples and explanations. The discussion also hints at potential homework-related constraints for some participants.

Who May Find This Useful

This discussion may be useful for students and professionals interested in signal processing, systems theory, and those seeking to understand the practical implications of inverse impulse response in various applications.

Can you please post an example of what you mean? Also, if this is for homework or coursework (sounds like it is), I can move your thread to the Homework Help forums.
 
The impulse response is basically stimulating a system with a unit impulse. The output when you do this is nothing more than the impulse response. So taking the inverse impulse response which is effectively 1/h(t) is the same as 1/y(t) which is the inverse of the output of the system.

ok i know that it related to the impulse but i need a practical example in application of use the inverse impulse response such somthing in image ( i need a live using of it )
I mean aclearly reasone for using it?

Google is our friend. I googled "inverse impulse response", and got some hits. This one off of the 2nd page of hits looks like it might be what you are looking for in an application:
