Flat top function

A flat top window is a partially negative-valued window that has minimal scalloping loss in the frequency domain. That property is desirable for the measurement of amplitudes of sinusoidal frequency components. See more In signal processing and statistics, a window function (also known as an apodization function or tapering function ) is a mathematical function that is zero-valued outside of some chosen interval, normally symmetric around … See more When the length of a data set to be transformed is larger than necessary to provide the desired frequency resolution, a common practice is to subdivide it into smaller sets and … See more Conventions: • $${\displaystyle w_{0}(x)}$$ is a zero-phase function (symmetrical about $${\displaystyle x=0}$$), continuous for • The sequence See more • Harris, Frederic J.

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 lens is a lens whose flat shape allows it to provide distortion-free imaging, potentially with arbitrarily-large apertures. The term is also used to refer to other lenses that provide a negative index of refraction. Flat lenses require a refractive index close to −1 over a broad angular range. In recent years, flat lenses based on metasurfaces were also demonstrated.
