Question

For given electric voltage signal dc value is

6.28 V
3.14 V
4 V
0 V

The correct answer is: 4 V

$V subscript d c end subscript equals V subscript a c end subscript equals fraction numerator 2 V subscript 0 end subscript over denominator pi end fraction equals fraction numerator 2 cross times 6.28 over denominator 3.14 end fraction equals 4 V.$
