cause a larger shift in the mean m of the distribution of the sufficient statistic. It

               was  shown  that  the  signal-to-noise  ratio  equals                 .  Thus,  one  way  to
               improve  the  detection/false  alarm  tradeoff  is  to  increase  the  SNR.  This
               conclusion is borne out in Fig. 6.2. Figure 6.3a illustrates the effect of increased
               SNR on the PDFs and performance probabilities under the two hypotheses using
               the same threshold as Fig. 6.1.
