What does a pole at the origin do?

2. A pole at the origin pi = 0 defines a component that is constant in amplitude and defined by the initial conditions.

What is pole Q?

For more complex systems such as wider filters, we can look at the Pole Q factor, which tells us about the performance of different parts of the filter response. A filter has a transfer function 𝐻(𝑠) which tells us what an output signal will look like for a given input signal.

What is Q value in DSP?

The “Q” control affects the bandwidth of a boost or cut. A small Q factor results in an effect on a wide frequency range, while a high Q factor allows to eliminate narrow-band flaws in the frequency response. The Q factor can be varied from 0.5 to 15 in 0.1 steps.

Is a pole at the origin dominant?

Dominant pole is a pole which is more near to origin than other poles in the system. The poles near to the jw axis are called the dominant poles. Or, get the closed-loop TF from Open loop TF.
