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.
