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.
