DIfference between Ac_Coupled and DC_Coupled transmission paths ?

An AC coupled path will have a capacitor in series in the path. Only AC will pass through & any DC levels will be blocked.
In a DC coupled path, everything flows through exactly as it comes in, including the DC levels of course.

what decides transmission path to be DC coupled and AC coupled ?

what decides transmission path to be DC coupled and AC coupled ?

What is this... some homework assignment ?

I have a lot of doubts here with out knowing more the answers here are futile to the best of my knowledge

In general if there is a Capacitor in parallel to the supply line it is a way of coupling the entire DC voltage into the other path to which the capacitor is connected in parallel

In that way you can easily discern a DC circuit almost all capacitors will be parallely fed to the ground to remove any noisy ripples in the op

But this is a poor way of discerning between AC and DC circuit in hybrid circuits
