Fwhm for gaussian
WebFeb 20, 2024 · 1 1 1 I assume you'd need to offset the signal to be centered at 0 before the FWHM calculation. However it seems that FWHM is a value generally computed for gaussians, and your data is very much not gaussian – Ander Biguri Feb 20, 2024 at 16:04 WebIn this video, I show the relationship between the full-width at half max of a Gaussian is 2.3548 times the standard deviation of the Gaussian.Follow me on ...

WebThe pulse width . is defined as the radius (HW1/e) at which the power decreases to 1/e or 0.37 of its peak power (φ pk) value. The temporal width is sometimes reported as its FWHM value, which—for a Gaussian pulse—is larger than . by a factor of 2 (ln2) 1/2. http://web.mit.edu/spm_v12/distrib/spm12/toolbox/FieldMap/pm_make_fieldmap.m
