The requirements on window length for resolving closely tuned
sinusoids was discussed in §5.5.2. This section considers
this issue for the Kaiser window. Table 3.1 lists the
parameter required for a Kaiser window to resolve equal-amplitude
sinusoids with a frequency spacing of
rad/sample
[1, Table 8-9]. Recall from §3.9 that
can be interpreted as half of the time-bandwidth of the
window (in cycles).
