Chebyshev and Hamming Windows Compared

Figure 3.28 shows an overlay of Hamming and Dolph-Chebyshev window transforms, the ripple parameter for chebwin set to dB to make it comparable to the Hamming side-lobe level. We see that the monotonicity constraint inherent in the Hamming window family only costs a few dB of deviation from optimality in the Chebyshev sense at high frequency.
