Lowpass filter design
Lowpass filter design
(OP)
I have designed a low pass butterworth flter(4th order) for a cut off freq. of 10Hz. Taking care that the gain of the filter should be -80db/decade.I am using a JFET opamp TL064. The problem is, I get the gain in postive and the signal isn't attenuated.I have designed also the passive components according to the specifications. Can any one give suggestions on this..
Thanks in advance

What is the Vpp of the input signal?

The 4th pin is the VCC of +12V and the 8th pin is the output of the opamp.4th order butterworth filter

Please advise on those.
