This module describes the recursive generation of the impulse response of a second order system.
Introduction
This module examines the recursive generation of the impulse response of a second order system. This analysis can be used to determine how to generate a cosine or sine function recursively.
Second order systems
The transfer function of a general second order system is given as:
The Direct Form II structure for the implementation of the second order system is shown in the following figure.
The difference equation for the second order system is
To recursively determine the impulse response of the system start with the following:
Then using Equation 3 the impulse response can be found recursively by:
For the values of
n >2 the recursive equation reduces to
because the values of
and
will all be zero for
n >2.
So, if you know the values of
and
, then the Equation 10 can be used to find future values of
.

nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale

Is there any normative that regulates the use of silver nanoparticles?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
