The dc present is given by:
2
dc = 1/2

v() d
0
For a sampled signal, the formula becomes:
i = n-1
dc = 1/n

v[i]
i = 0
Where n is the number of samples for an integral number
of complete cycles of the input waveform.
From these elementary values of W, rms and dc, the
following secondary values can be derived:
VA = V

x A

VAr =  (VA
