The Formula Explained

\( R_{xy}(n) = \sum_{m=-\infty}^{\infty} x(m) \cdot y(m+n) \)

Glossary of Variables

  • Signal A: The first input sequence of numbers.
  • Signal B: The second input sequence of numbers.
  • Cross-Correlation Result: The measure of similarity between the two signals.

How It Works: A Step-by-Step Example

To understand how the cross-correlation is calculated, consider two simple signals A: [1, 2, 3] and B: [4, 5, 6]. The cross-correlation function computes the degree of similarity between these signals at different lags.

Frequently Asked Questions (FAQ)

What is cross-correlation?

Cross-correlation is a measure of similarity between two signals as a function of the time-lag applied to one of them.

How do I use the cross-correlation calculator?

Input your signals into the calculator fields and click 'Calculate' to see the cross-correlation result.
