Characteristics of the Extended Basic System

2 Extended Basic System as an Information-Processing Unit 

The extended basic system is also designed to function as an informationprocessing unit with the same characteristics as those defined in Section 

2 for the basic system. The difference between the systems arises from the composition of the input signal. In the extended basic system the input signal can follow one of the four options presented in Table 4.11. These options were chosen as representative of the experimental systems studied (see Section 4.5). The concentration profiles applied here are also defined 

The analytical models developed in this part are based on those written for the basic system and presented in Section 4.1.3. The extended basic system is considered useful for information processing only with continuous operational modes. This is due to the fact that the inhibitor is not consumed in the reactor, and in a fed-batch reactor it accumulates and causes only decay effects. Therefore, the analytical model presented here refers only to a continuous reactor. 

Applying the compartmental analysis approach leads to equations (32) to (37), which hold for both the basic and the extended basic systems. When the latter is considered, the following equation should also be used
