- [Instructor] The reason we represent information like frequency response on graph, is so we can visually see how different quantities and values compare to each other. But sometimes scale and range of values can make graphs difficult to read. As a simple non-electrical example, let's say I want to compare the height of the buildings in my neighborhood. To do that, I could plot them on a chart. I live in a two-story house, that's about 25 feet tall. My neighbor has a one story house, that's about 15 feet tall. And there's somebody down the street that lives in a three-story town home, that's 35 feet tall. By plotting the height of these three houses on a chart, it's easy to visually compare them. I can see that the three-story house is more than twice as tall as the one story house. And that the two story house is in the middle height-wise. In this chart, I've represented the height of buildings along the vertical axis…
