Dear Experts, I have a basic doubt regarding common mode chokes(CMC) I understand that common mode chokes are used to cancel out the common mode noise. Can these CMC be used in differential pair? The data sheets of common mode chokes says these can be used in ISDN etc. How they work? Will they work similar to Ferrite beads? Regards Ananthoju --------------------------------- Do you Yahoo!?
