Poles of transfer function

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 is a pole of a system?

The roots of the denominator polynomial, d(s), define system poles, i.e., those frequencies at which the system response is infinite. Thus, p0 is a pole of the transfer function if G(p0)=∞.

What are poles and zeros in filters?

Poles and zeros are properties of the transfer function, and in general, solutions that make the function tend to zero are called, well, zeros, and the roots that make the function tend towards its maximum function are called poles.

What is a pole in electronics?

A poles is a frequency where the system has infinite response (at least mathematically, as the denominator goes to 0, the function goes to infinity).
