Just like what Jim says, unless you are FFT-ing the entire data set at once, without splitting the data into shorter frames, then you will most likely use the length of data set. A quick example is shown below. Ts = 50e-6; % Sampling Time (s) Fs = 1/Ts; % Sampling rate, Sampling Freq (Hz) f0 = 50; % Frequency of interest (Hz) duraT = 1 ...
WebMar 24, 2024 · The weighting functions also affect the amplitude of the sidelobes. With no weighting, the highest sidelobe is -13 dB below the spectral peak. The weighting functions reduce this with the Blackman-Harris weighting function reducing it to -67 dB. The selection of a window function depends on the user’s needs.

Hamming weight is used in several disciplines including information theory, coding theory, and cryptography. Examples of applications of the Hamming weight include: In modular exponentiation by squaring, the number of modular multiplications required for an exponent eis log2e+ weight(e). See more The Hamming weight of a string is the number of symbols that are different from the zero-symbol of the alphabet used. It is thus equivalent to the Hamming distance from the all-zero string of the same length. For the most typical … See more In error-correcting coding, the minimum Hamming weight, commonly referred to as the minimum weight wmin of a code is the weight of the lowest-weight non-zero code word. The weight w of a code word is the number of 1s in the word.
