## 1. DISCRETE SYSTEMS• When dealing with computers we will sample data values from the real world. These sampled values can then be used to estimate how a system will behave. • The term ‘discrete’ refers to the use of single sampled values, instead of a continuous functions. You will see that the difference is between weighted sums and integrals. ## 1.1 DISCRETE SYSTEM MODELLING WITH EQUATIONS## 1.2 DISCRETE CONTROLLERS## 1.3 BLOCK DIAGRAMS AND TRANSFER FUNCTIONS## 1.4 SAMPLING FUNCTIONS## 1.5 SYSTEM RESPONSE## 1.6 STEADY STATE ERROR## 1.7 PRACTICE PROBLEMS |
