Figure 5.12 : (A) Example of aliasing in the rod network. The first sinusoid is at the critical
frequency (0.5 c∕rod 0.03 c∕micron). The second sinusoid is aliased by the rods, causing
the second peak in the rod responses shown in figure 5.11. (B) Signal-to-noise ratio with
unit sinusoidal input and unit noise variance in each rod vs two-dimensional frequency
components. (C) A projection along the x axis of the plot in B.
