1. Discuss how block diagrams can help in determining the solution to difference equations.
2. What type of block diagrams are there to represent the difference equations?
3. How do different type of block diagrams (type 1 or type 2 etc) affect the realization of a real circuit.
4. When you observe the difference equations, do you see the multiply and add in the equations?
5. What are causal and non-causal systems?
