WebClick the "Find" button to trigger the calculations. A lag compensator decreases the bandwidth/speed of response: good to reduce the impact of high-frequency noise, bad if you want the system to react fast -> use lead compensator. Also, any high-frequency noise involved in the system is attenuated.
