Comment (by Fabricio):

 Could you please give an example showing the wrong behaviour of tf2zpk for
 too long inputs ?
 In addition, I don't understand why the following lines are in tf2zpk :
 {{{
 b = (b+0.0) / a[0]
 a = (a+0.0) / a[0]
 }}}
 as normalize contains
 {{{
 outb = b * (1.0) / a[0]
 outa = a * (1.0) / a[0]
 }}}
