Converter DAC... how works

akkex
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.

1. Homework Statement

Problem one (figure 1)

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?

2)Explain in detail the operation of a WATERFALL converter. Use a block diagram indicating how to carry out the conversion.

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

Problem two (figure 2)

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.
