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.

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.

You have written, as part of a school assignment, a research paper on the solar system. you want to share this paper on your school website. on which type of server will you upload it?

The following function returns a string of length n whose characters are all 'x'. give the order of growth (as a function of n) of the running time. recall that concatenating two strings in java takes time proportional to the sum of their lengths. public static string f(int n) { if (n == 0) return ""; if (n == 1) return "x"; return f(n/2) + f(n - n/2); } options: a) constant b) logarithmic c) linear d) linearithmic e)quadratic f)cubic g) exponential
