	I have problem with application of UAF42 unified circuit. I want use it as Butterworth NOTCH n = 8, 50 [Hz] bandwidth 2 [HZ]. I know that it is possible but I have problem with appropriate resistor and cappacitor seting.
I tryed  to use Your  Filter Pro program but the result was wrong and as consequence it worked as generator. Plase give me realy good applications.
