3. Bode diagrams

Representation in the Bode plane involves treating the modulus and argument of F (jω) separately as a function of frequency. This technique is not directly applicable to the case of a sampled transfer function F *(jω), which has an infinite number of poles.

3.1 Using the w-transform

Here we use the homographic transform (see Deterministic signals. Transforms and abacuses ) : $w = \frac{z - 1}{z + 1} = \frac{exp jω T - 1}{exp jω T + 1}$
