DFT Frequency Resolution Explained - Wave Walker DSP

WebIn gas adsorption, DFT is used to model the properties of the sorptive fluid, typically nitrogen, confined in porous solids [1-2]. Work to apply DFT to adsorption isotherms began in the 1980s with the work of Seaton et al. [3] who first proposed a procedure for determination of the pore size distribution of porous carbons from adsorption WebMar 16, 2024 · Introduction. Frequency resolution is defined as the ability to perfectly distinguish one frequency from another. The DFT frequency resolution is improved by increasing the signal length, not increasing the DFT size. The frequency resolution in radians of the DFT is. where N is the length of the input signal.
