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.

The figure below is my high frequency value:

Continue to adjust the value again, will achieve the goal.

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