5. 4.5 Design a combinational circuit with three inputs x, y, and z and three outputs A, B, and C. When the binary input is 0, 1, 2, or 3, the binary output is one greater than the input. When the binary input is 4, 5, 6, or 7, the binary output is two less than the input.

I don't understand this

(a) Digital Conversion, Sampling and Computer Architecture ADC RAM DAC DDR CPU ROM BIOS EDC (i) Which one of the above acronyms is a device you would not find in a computer? (ii) Six of the above are the most essential parts of a computer. List the six and give their full names. (b) Design a circuit to make an LED blink after 1 second forever. You can choose to use an Arduino microcontroller or only electronic components. In case of Arduino, draw a circuit diagram showing connections and give the code (graphical or sequential) as well. Otherwise, only make the circuit diagram. (c) The following figures show part of an analogue signal being digitised, at two different sampling rates. Make your explanation brief. (1) Explain how the difference in the sampling rates in figure 1 and figure 2 will affect the file sizes after digitisation. (ii) Which of the two sampling rates would you consider to be the least efficient to reproduce the original analogue signal accurately? (ii) What is the…
