I have a signal line AC waveform which goes something like -1.5 to +1.5V. Shown above as point "B". I've took it form the existing waveform switch (ramp, pulse, triangle, noise). Red color shows points where i "tapped in" my modifications. I need to DC offset it, so that it remains positive only. For that purpose i prepared 1.5V DC (shown in image above as "A").
What would be the most simple way to combine A + B?
In other words, to apply DC offset of 1.5V to AC signal. Of course without affecting the functionality of existing circuity.
Thanks!
