Thread: AC and DC signals
From my limited knowledge of electrical engineering, I'd say yes. DC coupling means both AC and DC current can pass through. It has no bearing on the polarity of the current (positive or negative) which I'm suspecting might have been why you asked? The opposite would be a problem though: DC signals can not pass through AC coupled inputs, because AC coupling has no direct path between input and output and will only allow AC current above a certain threshold frequency to pass through.
