The following question is related to "modern control systems 12th by Dorf and Bishop. You have 9 statmenet below, select only the onse that are true. Notice that they don't have numbers, so you have to be careful not to get things mixed.
O A good sampling frequency is one-half the frequency of interest. O Sa mpling at the Nyquist frequency provides good frequency information but not necessarily good amplitude information O A good starting point for sample interval selection is 4-10 samples per the time constant of the fastest transfer function in the system. O Difference equations, used in feedback control system applications, can be nonlinear O Phase lead compensators can reduce the lag present in a system. O Phase lead compensators can introduce higher levels of high-frequency noise into a system. O Phase lag compensators can introduce higher levels of high-frequency noise into a system. O An 8-bit digital sensor is one-half as accurate as a 16-bit sensor. The Ziegler-Nichols tuning method yields a system that overshoots by about 25% in response to a step input.Explanation / Answer
Phase lead compensators can reduce the lag present in a system
