IJ-o - the value of bandwidth, \i, which maximizes the output 

 SNR of a conventional pre-whitening 'bandlimited system fur each signal 

 slope '{,. (Eqn l8 and Fig. k) . 



■Y^-(M') - function proportional to the output SNE of a conven- 

 tional bandlimited pre-whitening system of bandwidth [i and with input 

 relative signal specti'al slope of g. The quantity yJ\i.)/y^{[i.o) is the 

 ratio of the output SNR of a pre-whitening system of bandwidth (a to the 

 output GWR of a pre-whitening system with optimum bandwidth M.o (Eqns. 

 16 and 17, Fig. *+)• 



b - multiplicative factor dependent upon t alone, which is 

 indicative of the performance of a bandlimited pre-whitening system 

 w.r.t. a true Eckart filter (Eqns. 30 and 3I). 



K^(p.") - a function which is the ratio of the output SNE of a 

 bandlimited Eckart filter of bandwidth M- to the output SNR of a true 

 Eckart filter with input signal spectral slope i, (Eqns. 3k, 35, and 36).
