For bandwidths where the side bands are contained within the filter skirts, the restric-
tions on ripple voltage are not so great. In this case, the side bands should be at least
10 dB below the filter skirts. Table 4.10 shows the maximum ripple voltage which
meets these requirements,
in
terms of bandwidth and frequency range.
