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.

Welcome to PF.

Our homework helpers can give you hints, or they can show where your work is wrong, but they are not allowed to just give you the answer. If you want help, attempt a solution and show us your work.

Could you also post the figures? I design data converters for a living and I've never heard of a WATERFALL converter. It must be another name for something else, but I can't help if I don't know what the problem is asking.
