1.Se requiere implementar un conversor unipolar que tendrá una tensión analógica variable entre 0 y 2 V pico. Deberá tener una relación señal / ruido de 47 dB. El rango de frecuencia será el de la voz humana. Determinar: a. Características del conversor.
b. Con los valores seleccionados, ¿Cual será el Nro binario que represente la tensión media?
c. y cual el que represente el valor de 1.45V.
d. Suponiendo que se trata de un DAC, ¿Cuantos resistores se necesitan? Si hay mas de una posibilidad expresar ambas.

Lucas put a lot of thought into the design for his company's new white paper. he made sure to include repeating design elements such as color schemes and decorative images. his goal was to a.add symmetry b.create a unified publication c.provide consistency d.save money

The idea that, for each pair of devices v and w, there’s a strict dichotomy between being “in range” or “out of range” is a simplified abstraction. more accurately, there’s a power decay function f (·) that specifies, for a pair of devices at distance δ, the signal strength f(δ) that they’ll be able to achieve on their wireless connection. (we’ll assume that f (δ) decreases with increasing δ.) we might want to build this into our notion of back-up sets as follows: among the k devices in the back-up set of v, there should be at least one that can be reached with very high signal strength, at least one other that can be reached with moderately high signal strength, and so forth. more concretely, we have values p1 ≥ p2 ≥ . . ≥ pk, so that if the back-up set for v consists of devices at distances d1≤d2≤≤dk,thenweshouldhavef(dj)≥pj foreachj. give an algorithm that determines whether it is possible to choose a back-up set for each device subject to this more detailed condition, still requiring that no device should appear in the back-up set of more than b other devices. again, the algorithm should output the back-up sets themselves, provided they can be found.\
