Sketch g with Matlab: Convolution of 3cos(10pi t) & delta(t+1/10)

Click For Summary

Discussion Overview

The discussion revolves around the task of sketching the convolution of the function \( g = 3\cos(10\pi t) \) with the delta function \( \delta(t + \frac{1}{10}) \) using MATLAB. Participants are seeking assistance with MATLAB code to perform this convolution.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant requests the full MATLAB code to perform the convolution, expressing a desire for a clear example to follow.
  • Another participant suggests that the "Similar Threads" section on the forum may contain helpful information and provides links to external resources related to convolution.
  • A later reply indicates that the original poster has already reviewed the suggested resources and is still seeking direct assistance with the coding task.
  • Another participant mentions that there is sample code available at the bottom of one of the provided links, highlighting the structure of the code for establishing functions, performing convolution, and displaying results.

Areas of Agreement / Disagreement

Participants generally agree on the need for MATLAB code to perform the convolution, but there is no consensus on the adequacy of the provided resources, as one participant expresses frustration with them.

Contextual Notes

Some participants express limitations in the resources they have reviewed, indicating that they did not find the information helpful for their specific needs.

Believe me, I've gone through those two pages before I post this. I have the second link even bookmarked. It still didnt help me. Can some1 just show me how the code should be written?

Well, there's sample code at the bottom of that second link. The first part (of the snippet) is establishing the functions, the stuff in the middle is the actual convolution (note how short it is), and the last bit is displaying the results.
