👉 Convolution is a mathematical operation that involves two or more signals, represented by functions of time, and produces another signal. In other words, it combines two or more signals to create a new signal that represents the composition of the original signals.
For instance, consider two signals x(t) and y(t), where x(t) is an input signal and y(t) is the output signal:
x(t) = f1(x(t)) + f2(x(t))
y(t) = g1
