18.8.1 The Correlation Dialog Box

Dialog Theme	See Dialog Themes.

Recalculate	See Recalculating Analysis Results.
Input1	Specifies the first input signal. See Specifying Your Input Data.
Input2	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.
Sampling Interval	Specifies the sampling frequency. The default is <auto>, which corresponds to an automatically-calculated interval.
Options	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].
Output	Specifies the output. See Output Results.
