FIGURE 5.22 Noise-free frequency estimation performance of quadratic
interpolator M = 30. (a) Minimally sampled case (K = 30), (b) oversampled
case (K = 64).
Figure 5.23 shows the amplitude estimation performance for the same
cases. Figure 5.23a shows that the interpolator reduces the worst-case straddle
loss from 3.92 to 3.22 dB when no window is used, and from 1.68 to 0.82 dB
