hi,all.who know the difference of the leapfrop and two opamp biqua filter,
at the energy,groupdelay,noise and gain ripple

Added after 31 minutes:

who know the difference of the two filter.
In my opion,leapfrop is better than biquad at gainripple,noise and energy,but is bad at groupdelay.

The physical implementation makes no difference. They all have the same ratio of polynomials as the transfer function.

The difference is in the effects of component tolerances and component count.
 

yes, i know. the same transfer. but the value of capcitor is different.the component count is different

and so the noise and groupdelay is different.

and who can tell me which one is more used in technology
