c. It is now possible to check that the selection of parameters will produce the required
logic by converting the set of parameters into a logic diagram. The result of this process
is shown below in Figure 11-7 and can be compared to the “Logic for Virtual Output 4”
diagram (Figure 11-4) as a check.
