  1. definition - What is Convolution? - Mathematics Stack Exchange

    Sep 6, 2015 · 3 The definition of convolution is known as the integral of the product of two functions $$ (f*g) (t)\int_ {-\infty}^ {\infty} f (t -\tau)g (\tau)\,\mathrm d\tau$$ But what does the …

  2. Meaning of convolution? - Mathematics Stack Exchange

    I am currently learning about the concept of convolution between two functions in my university course. The course notes are vague about what convolution is, so I was wondering if anyone …

  3. What is convolution, how does it relate to inner product?

    Oct 25, 2022 · My final question is: what is the intuition behind convolution? what is its relation with the inner product? I would appreciate it if you include the examples I gave above and …

  5. Definition of convolution? - Mathematics Stack Exchange

    I think this is an intriguing answer. I agree that the algebraic rule for computing the coefficients of the product of two power series and convolution are very similar. Based on your connection, it …

  6. Proving commutativity of convolution $ (f \ast g) (x) = (g \ast f) (x)$

    But we can still find valid Laplace transforms of f (t) = t and g (t) = (t^2). If we multiply their Laplace transforms, and then inverse Laplace transform the result, shouldn't the result be a …

  7. real analysis - On the closedness of $L^2$ under convolution ...

    Since the Fourier Transform of the product of two functions is the same as the convolution of their Fourier Transforms, and the Fourier Transform is an isometry on $L^2$, all we need find is an …

  8. analysis - History of convolution - Mathematics Stack Exchange

    Jul 4, 2015 · It the operation convolution (I think) in analysis (perhaps, in other branch of mathematics as well) is like one of the most useful operation (perhaps after the four …

  9. Definition of Convolution - Mathematics Stack Exchange

    Aug 2, 2023 · I am currently studying calculus, but I am stuck with the definition of convolution in terms of constructing the mean of a function. Suppose we have two functions, $f ...

  10. fourier analysis - Convolution of a box function with itself ...

    How do I find the convolution of $\phi$ with itself? I tried to take the Fourier transform of $\phi$ and square it, then take the inverse Fourier transform. However, in the latter step I couldn't …
