Pole frequency

A pole frequency corresponds to a corner frequency at which the slope of the magnitude curve decreases by 20 dB/decade, and a zero corresponds to a corner frequency at which the slope increases by 20 dB/decade.

How do you find the pole frequency?

The formula is n = 60 x f /p where n = synchronous speed; f = supply frequency & p = pairs of poles per phase.

What is a pole vs a zero?

Poles and Zeros of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes zero respectively. The values of the poles and the zeros of a system determine whether the system is stable, and how well the system performs.

What does pole mean in filters?

Poles represent frequencies that cause the denominator of a transfer function to equal zero, and they generate a reduction in the slope of the system's magnitude response.

What is pole in circuit theory?

A zero of the impedance function indicates the possibility of a current without an applied voltage, therefore, a natural current. A pole of the impedance function indicates the possibility of a voltage without an applied current, therefore, a natural voltage.
