What is window function in digital signal processing?

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 the middle of the interval, usually near a maximum in the middle, and usually tapering away from ...

What is Bartlett window in DSP?

The Bartlett window is very similar to a triangular window as returned by the triang function. However, the Bartlett window always has zeros at the first and last samples, while the triangular window is nonzero at those points. For odd values of L , the center L-2 points of bartlett(L) are equivalent to triang(L-2) .

What is Hamming window in DSP?

The Hamming window is an extension of the Hann window in the sense that it is a raised cosine window of the form. (A3.10) with a corresponding spectrum of the form. (A3.11) The parameter a permits the optimization of the destructive sidelobe cancellation mentioned in the description of the Hann window.
