The Ladder showed worst result compare with other filters.

BTW The way to analyze the Ladder and derivatives explained here

What I do not like most? There are several things:

1) Changing the output level with different resonance setting
2) The ladder requires precise parts and tuning.
3) The phase graph is extremely clucky. It could be something wrong with my circuit yet.
