Unformatted text preview: transfer function? Results (cont.): Using the same technique used in labs 2 and 3 linearize the filter response to the step input function to find the value of the time constant, τ =RC. Using this value of RC create an Excel filter simulation of the filter you tested in the lab. Design your filter simulation so R and C are input variables. See the example spread sheet given on the class web site. You must demonstrate and explain this spreadsheet to the TA during your grading session. Show up a bit early and login to a computer in the lab and open the spreadsheet. 1. Plot the natural log of the error function, ln( Γ (t))=ln[(y(t)-y f )/(y-y f )] vs. time. Find the time constant from the slope of the error function after the start of the step input response....
