How to eliminate the peak of the band-pass filtered curve?

Hardware design
August 24, 2020 by Maja 558

According to the curve of each frequency band measured by the circuit in the figure, there will be a spike at 10HZ and 100HZ. Why is this affected? And the bandwidth in the 100K and 1M frequency bands is not enough. I don’t know what is going on?

Adjust R43, C30, C28, the value can change the passband, it will be possible.

To widen the high frequency bandwidth, the rcl resonant circuit and frequency need to be adjusted appropriately.
