Figure 9: The SNRs of the three combinations
and their sum as a function of the Fourier
frequency
. The SNRs of
and
are equal over the entire frequency band. The SNR of
is significantly smaller than the other two in the low part of the frequency band, while is comparable
to (and at times larger than) the SNR of the other two in the high-frequency region. See text for a
complete discussion.
