Question

The circuit shown can be used as a simple 3-bit digital-to-analog converter (DAC). The individual bits of the binary input word (b1 b2 b3) are used to control the position of the switches, with the resistor connected to 0 V if bi = 0 and connected to VREF if bi = 1. (a) What is the output voltage for the DAC as shown with input data of (011) if VREF = 5.0 V? (b) Suppose the input data change to (100). What will be the new output voltage?(c)Makeatablegivingtheoutputvoltagesfor all eight possible input data combinations.
