How frequency response can be obtained from poles and zeros?

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 and zero of a transfer function in Matlab?

First convert the poles and zeros to transfer function form, then call fvtool . Click the Pole/Zero Plot toolbar button, select Analysis > Pole/Zero Plot from the menu, or type the following code to see the plot. To use zplane for a system in transfer function form, supply row vector arguments.
