Curve Fit | Mode Indicator Menu

Mode Indicator | Clear Indicator

Clears (zeroes) the Mode Indicator in the lower left graphics area.

The Mode Indicator is used by the Polynomial methods on the Frequency & Damping tab for curve fitting FRF data at each counted resonance.

Mode Indicator | Smooth Indicator

Smooths the Mode Indicator to remove noise peaks. An exponential window is applied to the Mode Indicator to smooth it. (See Transform | Window Data | Exponential command for details).

Each time this command is executed, more noise peaks are removed but the resonance peaks will become wider, meaning that the modes become more closely coupled.
