168 CHAPTER 9. SPECTRAL ANALYSIS AND WINDOWING
You can spend a great deal of time tracking down all the window characteristics in various
DSP books, but we’ve collected the most important aspects of commonly used windows for
you in Table 9.1.
In keeping with the practice of other DSP texts, the table shows main lobe width in
normalized radian frequency (where π equates to F
s
/2), with N being the length of the
window, and the sidelobe level is shown in decibels. We don’t show all the defining equations
for the windows (which can be found in most theoretical DSP texts [2, 18]) because we’ll
discuss how you can easily create the windows you need using
