Explica las estabilidad de entrada acotada, salida acotada.

BIBO es para entrada acotada, salida acotada (bounded input, bounded output). BIBO estable es una condición, tal que cualquier entrada acotada nos da una salida acotada. Esto es que conforme nosotros pongamos una entrada estable, nos garantiza obtener una salida estable.

Para entender este concepto, primero debemos ver que significa exactamente acotado. Una señal acotada es cualquier señal tal que existe un valor donde el valor absoluto de la señal nunca es mayor para algún valor. Ya que el valor es arbitrario, lo que queremos decir es que en ningún punto la señal puede tender a infinito.

Una señal acotada es una señal para la cual existe un constante A tal que t f t A

Una vez que ya tenemos identificado lo que significa una señal acotada, debemos mover nuestra atención a la condición que un sistema debe poseer para garantizar que si una señal pasa a través del sistema, una señal acotada se presentara en la salida. Resulta que un sistema LTI continuo en el tiempo con una respuesta al impulso h t es estabilidad BIBO si y solo si

CondiciÓN de tiempo-continuo para estabilidad bibo

t h t
Esto es decir que la función de transferencia es absolutamente integrable .

Extendiendo este concepto a tiempo- discreto tomamos la transición estándar de integración a sumatoria y obtenemos la función de transferencia h n , que debe ser absolutamente sumable . Esto es

Estabilidad y laplace

La estabilidad es muy fácil de deducir desde la gráfica de polos y ceros de una función de transferencia. Laúnica condición necesaria para demostrar la estabilidad es demostrar que el eje- ω es en la región de convergencia

Ejemplo de una gráfica de polos y ceros para un sistema estable de tiempo-continuo.
Ejemplo de una gráfica de polos y ceros para un sistema inestable de tiempo continuo.

Estabilidad y la transformada z

La estabilidad para las señales de tiempo-discreto en el dominio-z es tan fácil de demostrar como lo es para las señales de tiempo-continuo en el domino Laplace. Sin embargo en lugar de la región de convergencia ROC (region of convergence) necesaria para contener el eje- ω , la ROC debe contener el círculo unitario.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
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.
what is the actual application of fullerenes nowadays?
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.

is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
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?
how to fabricate graphene ink ?
