CMG-5T

In this equation zn are the roots of the numerator polynomial, giving the

zeros of the transfer function, and pm are the roots of the denominator

polynomial giving the poles of the transfer function.

In the calibration pack, G is the sensitivity given for each component on

the first page, whilst the roots z

and p

, together with the normalising

factor A, are given in the Poles and Zeros table. The poles and zeros given

are measured directly at Güralp Systems' factory using a spectrum

analyser. Transfer functions for the vertical and horizontal sensors may be

provided separately.
