The
$z$ -transform might seem slightly ugly. We have to worry about the region
of convergence, and we haven't even talked about how to invert it yet (itisn't pretty). However, in the end it is worth it because it is extremely useful in
analyzing digital filters with feedback. For example, consider the system illustrated below
Hence, given a system like the one above, we can pretty much
immediately write down the system's transfer function, and we end up with arational function, i.e., a ratio of two polynomials in
$z$ . Similarly, given a rational function, it is easy to realize this function in
a simple hardware architecture. We will focus exclusively on such rational functions in this course.
Questions & Answers
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.

what is the Synthesis, properties,and applications of carbon nano chemistry
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
