Design of band pass filter using pole zero method

Using pole-zero method, design a band pass filter to meet the following specifications:

• Complete signal rejection at direct current and 250Hz
• A narrow passband centred at 125Hz
• A three-decibel bandwidth of 10Hz

Assume sampling frequency of 500Hz

Matlab code for the for the following filter

It’s also not trivial. See: Wai-Kai Chen Passive and Active Filters — Theory and Implementations Wiley 1986 ISBN 0-471-82352-X.
