Can some please explain this equation in brainlet terms? My brain

What do you not understand?

sum of the pointwise multiplication of one signal and the reversed, shifted (by n) version of another.

Probably exists in a code library somewhere anyways desu. But it would be nice to understand this stuff.

My dads room used to be like this. He has a bachelors in comp sci from a university at DC, and has been coding for almost 40 years.

But he had a whole wall filled up with monitors/towers.

basically the equation in its entirety.

I don't understand the summation sign, the limits to +/- infinity and those square brackets. Also don't understand what a, v, n and m mean

So, I recently visited a lecture about convolution (that was part of a bigger event) in sound. I'm pretty new to these fields but from seeing Fourier mentioned in the text I am correct to assume that this is the same principle as the one in sound engineering?

best green text advice one can get. try somewhere else.

Consider f(x) = x^2 + 3x + 7 and g(x) = x^3 + x^2 + 7x + 9. Now multiply them to get h(x) which will obviously be another polynomial. Say you want the coefficient of x^3 in h(x). Take the 7 from f(x) and x^3 from g(x) and multiply them to get 7x^3. Take 3x from f(x) and multiply with x^2 from g(x) to get 3x^3. Take x^2 from f(x) and multiply it with 7x in g(x) to get 7x^3. So the coefficient of x^3 in h(x) will be 7 + 3 + 7 = 17. If you let A(k) denote the coefficient of x^k in a polynomial a(x), you can see that we've just computed H(3) to be F(0)G(3) + F(1)G(2) + F(2)G(1). Which is just the convolution of F and G. Now do the same with an infinity of coefficients.

Convolution is a pain in the ass except for when you're working with a few functions like deltas.
