Hi, I currently am having a problem where I wish to combine an AC signal and a DC signal. What I would like to know, is what parameters must be performed to combine the two together in a format where it would be akin to adding two waveforms. Aka, if I were to have a 1 Amplitude, Sine waveform(AC current), and then a flat line signal(DC), then how would I in a very basic electronic circuit (1 input current of the AC, another of the DC), so that they would in turn form a new Sine waveform AC current, that had an amplitude of 0.5 (effectively. added together the two waveforms.) From theory and what I've read from multiple (though unclear) sources, is that to do this I need to give them similar voltages, particular in the AC a similar Instantaneous and Average voltage as the DC current. Is this correct? If not, what is the proper theory, and real world method for combining these currents into one? Thank you for your time!
