[QUOTE="akkex, post: 6036330, member: 649191"] [SIZE=5][I]Hi guys! I´m doing a project of electronics if anyone can help me to realize it or to see the theory questions i can try to do it.[/I][/SIZE] [B] [U][SIZE=5]1. Homework Statement [/SIZE][/U][/B] [B][SIZE=7]Problem one (figure 1)[/SIZE][/B] [SIZE=6][/SIZE] [SIZE=5]1)Two DACs are connected in the manner indicated in figure 1: a)Deduce Vo based on Vb and B (t). b)For what values of B is V0 defined?[/SIZE] [SIZE=5]2)Explain in detail the operation of a WATERFALL converter. Use a block diagram indicating how to carry out the conversion.[/SIZE] [SIZE=5]3)The digital conversion of a signal with the following characteristics is desired: Maximum frequency: 10 Mhz. Signal noise ratio S / N = 60dB. a) How many samples should be taken? b) What is the minimum number of bits of the conversion? Argue your answers[/SIZE] [B][SIZE=7]Problem two (figure 2)[/SIZE][/B] 1)Explain in detail the operation of a waterfall converter. Show that the conversion takes place 2)In the circuit of figure 1 determine Vo in terms of B and Vref 3)In an industrial installation it is necessary to send to the process control five signals of a chemical reaction. The signals and their specifications are as follows: Sign # 1: Reaction temperature (Tr). The maximum frequency of the same one is of 10 Hz. 8 bits of conversion. Signal # 2: Pressure in the reactor (Pr). The maximum frequency of the same one is of 10 MHz. 8 bits of conversion. Signal # 3: Inlet flow # 1 (Qi1). The maximum frequency of the same is 10 KHz. 8 bits of conversión. [h2]Homework Equations[/h2] Thévenin ! [h2]The Attempt at a Solution[/h2] I do not know [/QUOTE]
