Half width at half maximum (HWHM) is half of the FWHM if the function is symmetric. The term full duration at half maximum (FDHM) is preferred when the independent variable is time. FWHM is applied to such phenomena as the duration of pulse waveforms and the spectral width of sources used for … See more In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum … See more Normal distribution If the considered function is the density of a normal distribution of the form Other distributions In spectroscopy half the width at half maximum (here γ), HWHM, is in common use. For example, a See more • Gaussian function • Cutoff frequency See more • FWHM at Wolfram Mathworld See more WebBecause the preflight slit functions vary continuously with wavelength, the ranges of preflight slit function FWHM within the spectral window are plotted as the gray bands.
