Este modulo examina la idea y detras de la formula de reconstrucción perfecta más a fondo.
Introducción
En el modulo previo en
reconstrucción , dimos una introducción de como trabaja la reconstrucción y temporalemte derivamos una ecuación usada para realizar una perfecta reconstrucción. Ahora tomemos un vistazo más cercano a la formula de la reconstrucción perfecta:
Escribiremos
en términos de las funciones sinc desplazadas y escaladas

Formulas de la derivada de reconstrucción
¿Que es
Este
producto interno puede ser difícil de calcular en el dominio del tiempo, asi que usaremos el
Teorema de Plancharel
si
si
En la
usamos el echo de que la integral de la senosoidal en un intervalo completo es 0 para simplificar nuestra ecuación.
Así,
Por lo tanto
es una
base ortonormal (ONB) para el espacio de funciones limitadas de banda de
.
Muestreo es lo mismo que calcular los coeficientes de ONB,
que es el producto interno con sincs
Resumen

Para poder entender un poco más sobre como podemos reconstruir una señal exacatamente, será útil
examinar la relación entre las transformadas de Fourier (CTFT
y DTFT) a más profundidad.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Where is quantity of cut flower produced, I is labour input and K is fixed capital input (K-5). Determine the average product of labour (APL) and marginal product of labour (MPL)
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏
Asui
it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs
Awais
thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
