Convolution Integral Example 04 - Convolution in Matlab (2 Triangles)

This example also computes the convolution of two triangle functions, i.e. y(t) = x(t)*x(t) where x(t) are triangle signals and * is the convolution operator. This is the same problem examined in Convolution Integral Example 03.

However, convolution is performed in Matlab in this example. We show how to appropriately account for the sampling interval (i.e. dt) when using the Matlab convolution operator.

The final convolution plot from Matlab is compared to the analytic results obtained in the previous example, and as expected, they match.

You're an absolute master, my friend. Just saved me several hours of reading forums.

Thank you...This is really good tutorial, have been struggling with this for long, you can explain really well.

[TezujsrvT]

your explanation is quite really it helped me in my signals and systems lab....hoping for more videos like this on different topics in (s and u very much

[saras]

That was was just what I was looking for!!! thanks for uploading!

[jean.carlo]

Thank you very much, you really helped me

In the 20th line of code, what have you entered at the beginning of the bracket? is it 'goa'?

[eslamattia]

i need a code for "discrete" convolution by building the function by your self not using the "conv" built in function, can you help?

[jcluk]

How does the "median(diff(t))" in line 27 make the discrete convolution become the continuous time convolution?

I need learn about linear time invariant systems ( LTI ), finite impulse response ( FIR ) and IIR ( infinite impulse response  ) can you help me? thank you very much
