Expert Solution

Step 1

In 3-bit converter, there are 8 possible combination which is 2³. For the D/A converter shown in the circuit there are 8 resistance and the combination of switches are:

8 switches in first row,
4 switches in second row,
2 switches in third row.

Thus, the generalized relation for n-bit D/A converter is:

Number of resistors = 2ⁿ,
Number of row of switches = n,
Total number of switches (s) is:
