The Correlation Dialog Box

See Recalculating Analysis Results.

Specifies the first input signal. See Specifying Your Input Data.

Specifies the second input signal. If you would like to calculate auto-correlation, this should be the same as the first input signal. See Specifying Your Input Data.

Specifies the sampling frequency. The default is <auto>, which corresponds to an automatically-calculated interval.

Specifies the computation options.

Type

Specifies whether to compute a linear correlation or a circular correlation.

• Linear: This is suitable for signals whose data points outside the input range can be viewed as zeros.
• Circular: This is best suited for signals that repeat periodically.

Normalize

Specifies whether the result should be normalized to [0, 1].

Specifies the output. See Output Results.
