It is seen in Figure 4(a), that upon changing [L.sub.2] keeping other parameters constant, the lower notch band moves keeping upper notched band unaffected.
The maximum value of group delay is about 7 ns at center frequency of the notched band.
This means that the resonant frequency drops by 56.7% by increasing the lumped capacitor that varies from 0.01 to 0.6 pF, with the same compact size, so inserting lumped capacitor leads to changing the notched frequency as shown in curve fitting in Fig.
Overall, there were 113,818 (15.3%) notched LE audiograms and 108,616 (14.6%) notched RE audiograms, which is about half the prevalence of notched audiograms found with the 3,430 veterans involved in our earlier study in which 28.8 percent of the LE audiograms and 27.1 percent of the RE audiograms were notched at 4,000 Hz [28, p.
