Instrument Response
Instrument Response : In order to recover the ground motion at a recording site, one must deconvolve (See: Deconvolution) the contribution of the recording instrumentation. A modern instrument response can be broken down into two stages: a) the transformation of ground motion to an electrical energy followed b) by the transformation of that electrical energy into an output signal which can produce a permanent record (historically paper or photographic record, today mostly a digital stream recorded on a computer storage unit). See: Chapter 5 of this Manual as well as Wielandt (2002), Scherbaum (2002), and Eq. (3.10) in Ben-Zion (2003)
