Let's build a pole zero model with the following characteristics:
Key | Value |
---|---|
GAIN |
5 |
POLES |
(f = 1 Hz, Q = 2) |
ZEROS |
(f = 1 Hz), (f = 0.1 Hz) |
Now let's build our first pole/zero model which has a complex pole at 10Hz of Q=2, and two zeros, one at 1Hz, one at 0.1Hz.
m = pzmodel(5, [10 2],{1, 0.1})
We can easily obtain the response of this transfer function by using the 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
