I know that a resistive optoisolator can be used to transfer AC, but what about those DIP packaged phototransistor optocouplers? If I'm sending the signal optically to the base of the transistor, what do I need to do to get that same signal out of either the collector or emitter? Would a circuit like this:
be the best way to go or is there a better way? I should mention that the signals I want to send have a DC offset, they never go below ground.
