1. The problem statement, all variables and given/known data In the figure, the Bode plots of a continuous-time plant (thin line) and of its discrete-time counterpart, representing the discrete-time operation of the plant preceded by a Zero Order Hold (ZOH) (bold line), are displayed. What is the Sampling time used? 2. Relevant equations I figure it has something to do with f= 1/T, but other than that im really not sure how to use it with the bode plot, any pointers would be great!
