    I am having a hard time understanding the concept of dc blocking and AC coupling. If there is a dc blocking cap between amp stages. The DC current can not get through the insulating material and as such blocks it. How then does the AC signal get coupled through this same capacitor insulating material. I am looking for a precise answer, this seems like a simple question, but i can not get a real answer that explains it. Please help
