Is there a process for deriving special cases of convolution?

1. What is the process of convolution?
2. Which method can be used determine the convolution between two signals?

What is the process of convolution?

Convolution is a mathematical way of combining two signals to form a third signal. It is the single most important technique in Digital Signal Processing. Using the strategy of impulse decomposition, systems are described by a signal called the impulse response.

Which method can be used determine the convolution between two signals?

Cross Correlation Function

Cross correlation is the measure of similarity between two different signals.
