Documentation

FlatTop is the FlatTop window class. The float top window is most useful for calculating the spectral amplitude of a peak with little spectral energy in nearby bins and provides the best amplitude accuracy in this case.
FlatTop(void)
Construct a flat-top window.

FlatTop(int N)
Construct a FlatTop window object. Initialize it for sequences of length N.

~FlatTop()
Delete the window and release any allocated storage.

double WinFc(double arg)
Return the window function at x, where x = 2*pi*i/(N-1). The FlatTop window is 0.2810638602 - 0.5208971735*cos(x) + 0.1980389663*cos(2x).

This class has no child classes.
