WebA chirped Gaussian pulse is well described by Eq. (3.2.15) with C = 5 and = 50 ps. Determine the temporal and spectral widths (FWHM) of this pulse. 3.3 Prove that for an unchirped Gaussian pulse of arbitrary width, the product approximately equals 0.44, where Δ t and Δ ν are the temporal and spectral widths (both measured as FWHM), respectively. Webtc = gauspuls ('cutoff',fc,bw,bwr,tpe) returns the cutoff time tc at which the trailing pulse envelope falls below tpe dB with respect to the peak envelope amplitude.
