I have written a script to set and measure an IIR filter in the moku froma continuous time transfer function in zpk form. The script can be found in labutils and attatched to this post.

The following transfer function is:

z = [-500,-35000,-50000+40j , -50000-40j]

p = [-1000,-12000,-80000+40j , -80000-40j]

k = 1
