ADC = Analog to Digital Conversion. This can be any signal, DC, AC, Audio, Video, converted to a digital format.

 

You might get some benefit from reading about A to D conversion. Here is a link into our Ebook about the subject - http://www.allaboutcircuits.com/vol_4/chpt_13/4.html.

Your question about sampling frequency and the counter frequency is hard to answer. What do you mean by "counter frequency"
