Mimo transfer functions are regarded as arrays of siso transfer functions one per i o channel each of which is characterized by its numerator and. The cutoff frequency is 1 khz which in normalized frequency is 0 2 pi radians sample. The transfer function for the series circuit is h z v z x z y z v z h1 z h2 z h2 z h1 z where the commutative property of multiplication implies that the order of the filters may be reversed.

If you design an fir filter in matlab then you have the z transform coefficients the coefficients of the polynomial in z 1. Numerical methods using matlab george lindfield john penny. The matlab function zplane can display the pole zero diagram example.
