Figure 2.11. This is a graph. The horizontal axis is labeled Frequency in Megahertz and goes from 0 to 1. 0.5 MHz is exactly half way across the graph making it a linear scale. The vertical axis is labeled Attenuation ratio A sub R. it also goes from zero to one and is linear. The data curve begins at A sub R = 1 and frequency = zero. It goes straight down the left line departing from the left hand line at about A sub R = 0.2. What follows is an approximate reading of the graph without regard to the equation that generated the line. The values are read in the order Frequency, A sub R. 0.01, 0.15. 0.02, 0.1. 0.03, 0.05. 0.04, 0.03. 0.05, 0.02. The data line merges with the frequency axis at about 0.1. It goes all the way to 1 on the A sub R = 0 line. End verbal description.
