The former is 1 Supported in part by the Murata Science Foundation. - r + f e \\Phi \\Phi - C(z) - H - P (s) q y - 6 \\Gamma Figure 1. Unity Feedback Sampled-Data System denoted by the slanted line segment while the latter is designated by the box H. The objective here is to analyze and design this control system. The lecture started out with the introduction of z-transform, description of how we can compute the z-transform from a given Laplace transform, and then proceeded to the z-domain representation etc. I can still recall with a rather vivid image that I
