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?
