Here’s the paper describing it.

In it, there are plots of its amplitude response that might help you understand how
it work.

The best way to use it is in series, e.g.

 aleq eqfil al,    75,  75,ig1
 aleq eqfil aleq, 150, 150,ig2
 aleq eqfil aleq, 300, 300,ig3 
 aleq eqfil aleq, 600, 600,ig4
 aleq eqfil aleq,1200,1200,ig5
 aleq eqfil aleq,2400,2400,ig6
 aleq eqfil aleq,4800,4800,ig7
 aleq eqfil aleq,9600,9600,ig8
 al   eqfil aleq,15000,10000,ig9
