Hi,

 

I would like to design a BPF using ADI filter wizard.

The spec are shown as following.

1.Passband : 100 ~ 3500Hz, -0.3dB, Center Frequency = 1800Hz

2.Low pass filter, cut off frequency : 40KHz, -40dB

3.High pass filter, cut off frequency : 16Hz, -40dB

 

I perform a example:

But it seems the high pass cut off freq cannot achieve 16Hz.

Could someone help me to check it?

Thanks.
