Let's build a pole zero model with the following characteristics:
Key | Value |
---|---|
GAIN |
5 |
POLES |
(f = 10 Hz, Q = 2) |
ZEROS |
(f = 1 Hz), (f = 0.1 Hz) |
Our pole zero model has a pole at 10 Hz with a quality factor of Q = 2, and two zeros, one at 1 Hz, one at 0.1 Hz.
m = pzmodel(5, [10 2], {1, 0.1})
We can easily obtain the response of this transfer function by using the pzmodel/resp method.
resp(m)
The result is the figure shown below.
The quality factor notation comes from the mechanical analogy of the harmonic oscillator. In short, we can classify systems in terms of Q as
