WebMay 18, 2024 · A flat top is a type of cooking range whose surface is sort of a cross between a griddle and a grill. Unlike a grill, a flat top doesn't have a grate, but simply a flat cooking surface. And unlike a griddle, you can … WebThe coefficients of a flat top window are computed from the following equation: where 0 ≤ n ≤ L − 1. The coefficient values are: Flat top windows have very low passband ripple (< 0.01 dB) and are used primarily for calibration purposes. Their bandwidth is approximately 2.5 times wider than a Hann window.
WebA flat top guitar is a type of guitar body model which has a flat top (as opposed to archtop).

But they are not good for avoiding scalloping loss. To avoid scalloping loss, you need a flat-top window. Wikipedia has an example of a flat-top window. Narrower flat-top windows could be created, though they wouldn't be as flat.
WebFlat top laser beams also do not remain constant under transformations; consequently, the beam profile of an incident flat top beam is not naturally preserved as the beam propagates.
