Convolution of box signal with itself by Brian Amberg. Derivative work: Tinos, CC BY-SA 3.0 https://creativecommons.org/licenses/by-sa/3.0, via Wikimedia Commons FAQ Is convolution commutative? Yes, convolution is commutative, meaning that the order does not matter and that f∗g=g∗f....
We have a solution.It’s been known for a long time that convolving a signal with white noise gives reverb, but this was usually seen as more of a curiosity without that much practical use. White-noise reverb tended to be bland, and get lost in a mix due to its slightly muddy ...
Time Domain Signal Processing with the DFT FREDERIC J. HARRIS, in Handbook of Digital Signal Processing, 1987 A Discrete Linear Convolution and Correlation The expression for computing the linear convolution of the sequence h(n) of length L, denoted [h(n):L], and the sequence x(n) of arbi...
Convolution is a commutative operation [i.e., f (x) * g (x) = g (x) * f (x)]. The result of convolving two functions can be considered as the area under the curve that is obtained by multiplying one function with a reversed (in α) and shifted (by x) version of the other...

A 2nd order filter on a 1D signal (ex: audio) would be a matrix dot product sliding across the 1D signal outer producted with itself. A 1st order filter on a 3D signal (ex: video) would be a 3D block of numbers that slides over the video. The filter's dimensionality is the order...
Sampled-acoustics convolution processors are a different type of digital reverb than the digital reverbs that preceded them. They are much more calculation-intensive, but they offer the ability to faithfully convolve any given impulse response with any input signal. The Impulse Response (IR) of a...
Vehicle re-identification (Vehicle Re-ID) aims at retrieving and tracking the specified target vehicle with multiple other cameras, which can provide help in checking violations and catching fugitives, but there are still the following problems that need
In the CSTR example above that was a reasonable assumption, but in general it is not. Yet another way of solving the problem of missing data at the edges of the signal is to think of the signal as something that repeats itself. After the end of the signal, we will suppose it starts ...
