6. Don’t know Transfer Function of Cascaded
Systems
Consider a system that is itself a cascade of two
systems. What is the transfer function of the system.
That is, if the input to the system is a unit exponential,
what is the output?
est
G
F
?
My confidence that I have the correct answer is:
1. 100%
2. 80%
3. 60%
4. 40%
5. 20%
6. 0% Transfer Function of Cascaded
Systems
The transfer function of the system
est
G
F
?
is F (s)G(s), since the output of the system is
F (s)G(s)est . My answer
1. Was completely correct
2. Was mostly correct, with one or two
minor errors
3. Had many errors
4. Was completely incorrect
