The TWNDOW command allows the source trace array to be modified so the amplitude of the trace endpoints
gradually diminish to zero.
The TWNDOW command formats trace arrays with one of three built-in "window" algorithms: HANNING, UNI-
FORM, and FLATTOI? Each simulates a series of equally spaced filters (see figure below). The detected, spectral
line traces the top of the passband while moving from NAf to (N + 1)Af.
