Texts: 0.5z
(a)
Given the function F(z), find the value of z in the expression 0.5z - 0.7.
(b) Considering the cascaded zero-order hold (z.o.h) sampled-data transfer function, G(z) = (z / R(z)), where R(s) is shown in Figure 4.
(c) Write the state equations for the plant described by the equation ay(t) dy(t) + 3 + yt = rt dt^2 p.
