Instrument response

Description

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)
