Fig. 9.

Histogram plots of the channel outputs with signal location variability and without anatomical variability. The extent and severity of the defects were both equal to 25%. The axes are as described in Fig. 4. The columns represent the outputs from the six channels defined in Fig. 3. The rows are from (a) the anterolateral, (b) inferior, and (c) the mixture of anterolateral and inferior defects. Sixty-four histogram bins were used.
