quiz thursday 4/3/08 deals with difference equation and transfer equation and other similar stuffs
system realization: how to convert between systems and equations
X[z] (Fig1)
canonical form system
H=Y/X
steps to convert from canonical system to proper equations
1. label signal near end and work backward reversing operations (X` and z^nX` terms)
2. write equation to input and output of first sum block (summation)
3. write equation for input and output of second sum block
4. divide Y equation by X equation to get H[z] (transfer equation)
another example (Fig2)
go opposite direction given H[z] (Fig3)
add in time domain block diagrams (Fig4)
cascade form (Fig5)
parallel form (Fig6)
example (Fig7)
