NAFI TR-lUl^■0 

 Referring to the matched Eckart filter result (equation 29), one obtains 



Note that for 5 = §0 , equation hk reduces to unity, as it should. 



Equation kk is plotted in Figure 8. Cross reference to Figures 

 k and 5 show how the performance of a mismatched Eckart system compares 

 to a mismatched pre-whitening system. As an illustration, this has been 

 done for two design values of Z, in Table I, and these indicate the Eckart 

 system generally suffers less mismatching loss than the pre-whitening 

 system under either base line comparison.
