#X text 63 1 PULSE SPECTRUM MEASUREMENT;
#X text 16 377 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 16 442 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.;
#X text 17 518 The spectrum measurement is done in the "pd fft" subwindow
\, but see the "FFT examples" for information about that.;
