Imagine that you have trained a Bernese Mountain Dog (Bernie) to carry a box containing 3 small SSD cards (the real Swiss Bernie would of course carry a water bottle). Assume that each SSD card has a capacity of 7 GB of data. The dog can reach you (wherever you are) at a speed of 18 km/h. Your device's memory is full, and you need to transfer the data elsewhere. Assume you have access to a 150 Mbps (Mbits/s) data transfer channel. What distances would Bernie have a greater data transfer capacity than your regular 150 Mbps connection? You can ignore any extra network overhead (headers, error correction, etc.)

INSTITUT SUPERIEUR DE TECHNOLOGIE D'ANTSIRANANA ECOLE DU GENIE INDUSTRIEL MENTION TECHNOL OGIE DES COMMUNICATIONS SUJET D'EXAMEN : LOGIQUE SEQUENTIELLE Exercice 4 : Soit le circuit séquentiel de la figure 4. Ce circuit est réalisé avec trois bistables \( D \); it a une entrée \( x \) et trois sorties \( y 2, y 1 \), et yo. Figure 4 Soient \( y 2, y 1 \) et \( y 0 \) les valeurs des sorties au cours d'un cycle. Exprimer \( y^{\prime} 2, y^{\prime} 1 \) et \( y^{\prime} 0 \), les valeurs des sorties au cycle suivant en fonction de \( x, y 2 \), \( y 1 \) et \( y 0 \). Donner la table d'états correspondant à ce circuit. Expliquer en une phrase ce que fait le circuit. Comment pourrait-on simplifier ce circuit? Exercice 5 Réaliser un compteur modulo 3 , c'est-à-dire un circuit séquentiel donnant la séquence \( 0,1,2,0,1, \ldots \) Comment se comporte-t-il si son état initial est 3 ? Comment peut-on compléter ce circuit pour permettre de l'initialiser à une valeur arbitraire? Exercice 6 Réaliser un circuit séquentiel donnant la séquence \[ 0,1,2,3,4,5,4,3,2,1,0, \ldots \] Combien faut-il de bistables pour réaliser un circuit donnant la séquence indiquée ci-dessous ? \[ 0,1,2, \ldots, n-1, n, n-1, \ldots, 2,1,0, \ldots \] Réaliser un circuit séquentiel qui, après \( n \) cycles d'horloge, donne la représentation binaire de 11 * modulo 16.

Criteria for success: All curved arrows must be unambiguous and correctly represent the transformation. Elementary mechanistic steps must be correctly identified. The products of curved arrow mechanism must be correct. Hint: draw hydrogens and/or lone pairs of electrons to clearly show bond breaking and forming. Tasks 1. Draw curved arrows for the reactions and classify each step (numbers in circles) as one of the four elementary ionic reaction patterns. Explain why the equilibrium between carbocations favors carbocation B. 2. Draw all products of the reaction depicted by mechanism X.
