Abstract

The conditions under which the magnification of an electromagnetic seismograph can be changed without altering its response characteristics are discussed. It is seen that. this can be done only If (I) the selsmograph lS made up of a se18mometer and galvanometer of equal free periods and (2) the dampings of the seismometer and the galvanometer are also suitably altered, When sensitivity adjustments are so made, the maximum magnification is seen to be attained when damping of the seismometer is equal to that of the galvanometer and this does not generally go  with the maximum value of 11, the attenuation factor.
