If I have a string of 19 continuous bits 'high' followed by a bit 'low', how do I calculate the DC Offset if the pattern is repeated? Is it just [(19 - 1)*(the amplitude)]/(20)?
Thanks for the help.

Yes, that looks correct. You are just calculating the average value -- that would be the DC offset.

Don't you mean equivilent DC voltage value?
This would be the RMS value in a sine wave.
AFAIK DC offset has to do with symmetry of the waveform around 0.
It would be 50% of the high value if the low value is 0.
