WebHanning smoothing is a running mean across the spectral axis with a triangle as a smoothing kernel. The central channel is weighted by 0.5 and the two adjacent channels by 0.25 to preserve the flux; mathematically this is an N=5 sample Hann window kernel (including the outer-most zero-weight samples in the window). What is FIR filter in DSP? WebWikipedia is your friend: Hanning window Surely your googling came up with wikipedia?! Anyway just create a function that returns an array of length N with the Hanning … (see § Hann and Hamming windows) It is also known as the raised cosine window, Hann filter, von Hann window, etc.[2][3] Fourier transform[edit] Top: 16 sample DFT-evenHann window. Bottom: Its discrete-time Fourier transform (DTFT) and the 3 non-zero values of its discrete Fourier transform (DFT). See more The Hann function is named after the Austrian meteorologist Julius von Hann. It is a window function used to perform Hann smoothing.
