    Our policy is that each poster open a new topic for a new question. When you hijack an existing post, it can be confusing as to how and who to rely to.

    This is the original thread - http://forum.allaboutcircuits.com/showthread.php?t=17531

    You might state the upper and lower limits of the tuning limits, as well as filter bandwidth. What progress have you been able to make on your own?
