shows the ripple test with absolute ripple value displayed for Frequency Band 1. The B1
indicates that the ripple value displayed is for Frequency Band 1. Notice that Frequency Band 1 passes the
ripple test. It has an absolute ripple value of 1.675 dB while the maximum ripple value entered for Frequency
Band 1 was 2.0 dB. Thus, even though the ripple test fails because of Frequency Band 3, the ripple passes in
Frequency Band 1.
