👉 In mathematics, a convolution is a mathematical operation that takes two or more functions and produces a third function. It combines the outputs of these functions in a way that preserves their properties. Convolution can be performed on signals, such as signals representing time series data, to create new signals that are useful for analysis, synthesis, and communication. The term "convolvuluses" refers to this operation, which is used in signal processing, where it can be used to combine multiple signals into a single
