How do you read a pole-zero map?

By convention, the poles of the system are indicated in the plot by an X while the zeros are indicated by a circle or O. A pole-zero plot can represent either a continuous-time (CT) or a discrete-time (DT) system. For a CT system, the plane in which the poles and zeros appear is the s plane of the Laplace transform.

What are poles and zeros of a network?

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 are zeros and poles in Bode plot?

Zeros give a positive slope. Poles produce a negative slope. (log10 scale) 20 log(H) -20 db dec.
