👉 Convolution is a mathematical operation that takes two signals (x1, x2) and produces another signal. The convolution of two signals A(x) and B(x), denoted by A
B(x), is the result of applying the convolution operator to each input signal separately, then summing these results.
In other words, convolving refers to the process of combining or multiplying together elements from two or more signals based on their frequency components. The result of this operation is a new signal that
