The circuit shown in the figure is a 4-bit digital-to-analog converter. In this circuit to represent the

th digit of a binary number, a corresponding switch is either closed (1) or opened (0). (We start counting the digits from zero as shown in the figure.) For example, 1010 is represented by closing the switches

and

, while switches

and

are open. What are the voltages across the 1.0 resistor, for the binary numbers 0001,1000 and 0110 , respectively? (A)

(B)

(C)

(D)
