+#X text 14 357 Here is a measured amplitude spectrum for the pulse
+train. Nutice that \, other than a smallish spillover \, the energy
+sits in one "lobe" whose changing width justifies our calling the squeeze
+factor the "bandwidth.";
+#X text 16 428 The spectrum is in units of amplitude. THe sidelobes
+\, although they look small \, are actually only about 34 dB down.
+You can design more complicated pulse trains \, little Blackman window
+functions \, which control the sidelobes much better.;
