Web1 mrt. 1998 · Here is the Matlab for it: % Add a "Blackman window" % w = blackman (N); % if you have the signal processing toolbox w = .42-.5*cos (2*pi* (0:N-1)/ (N-1))+.08*cos (4*pi* (0:N-1)/ (N-1)); figure (5); subplot (3,1,1); plot (w,'*'); title ('The Blackman Window'); xlabel ('Time (samples)'); ylabel (' Amplitude '); text (-8,1,'a)'); WebThe paper identifies the first harmonic decade as the most affected by the leakage and concludes that among three window types: the rectangular, Hanning (utilized in the AD5933 design) and Blackman-Harris, the latter would produce a superior performance. The paper does not examine the frequencies below the lower limit of the first frequency decade.
