Cross-Correlation Calculator

Calculate cross-correlation to measure similarity between two signals at different time lags.

Input Signals

Signal x[n] (comma-separated)

Signal y[n] (comma-separated)

Show normalized values

Rxy[l] = Σ x[n]·y[n+l]

Quick Examples

Peak Cross-Correlation

26.0000

at lag = -2

Peak Normalized

0.9370

Time Delay

-2 samples

lag = -226.0000

lag = -120.0000

lag = 014.0000

lag = 18.0000

lag = 23.0000

lag = 30.0000

lag = 40.0000
