Learn why a logarithmic scale can be used to more easily display a wide range of values than a linear scale. Learn how to interpret information displayed on semi-log and log-log plots.
- [Instructor] The reason we represent information…like frequency response on graphs…is so we can visually see how different quantities…and values compare to each other.…But sometimes the 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 townhome 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 using a linear scale.…In a linear scale, the tick marks along the axis…are equally spaced…
