Hello experts!
Here is 3-bit digital to analogue converter.
I have a question related to this.
1)What does it mean if you have to say to perform operation on it with 101?
2)And we can obviously conclude and see output voltage on oscilloscope. But by calculation how can you predict the answer(i.e. output voltage)? Is there any formula?
3)And What is the criteria if I want to add 1 more resistor at input(making 4-bit DAC) either it is last or may be it is the first resistor. And of course adding another input resistor must change the value of feedback resistor, then what it should be?
