Figure 5.8. This is another log log Bode plot. The vertical axis is labeled gain and goes from 10 to the minus 1 at the bottom to 10 to the 4 at the top. The horizontal axis is labeled frequency and goes from 10 to the minus 2 at the left to 10 to the 8 at the right. There are two lines on this graph. The black one is labeled open loop gain and begins a little to the left of and below gain = 1 and frequency = 10 to the minus 1. It goes up on a slope of plus 1 to the point gain = 10 to the 4 and frequency = 10 to the 3. It runs horizontally to the point gain = 10 to the 4 and frequency = 10 to the 4. At this point it breaks down to a slope of minus 1 and ends a little below and to the right of gain = 1 and frequency = 10 to the 8. The red line is labeled closed loop gain and begins a little to the left of and below gain = 1 and frequency = 10 to the minus 1. It goes up on a slope of plus 1 to the point gain = 10 to the 2 and frequency = 10. It runs horizontally to the point gain = 10 to the 2 and frequency = 10 to the 6. At this point it breaks down to a slope of minus 1 and ends a little below and to the right of gain = 1 and frequency = 10 to the 8. End verbal description.
