A gaussian approximation of | H ( f )| in the form 
has been found to be accurate to at least the 0.75-amplitude point in the frequency domain. Using this relationship, plot P( f)/P(t) as a function of frequency from 0 to 1000 MHz for fibers that have impulse responses of full rms pulse widths 2 equal to 2.0, 1.0, and 0.5 ns. What are the 3-dB bandwidths of these fibers
