Abstract
The amplitudes of processing and digitization noise in strong motion earthquake accelerograms are reviewed for hand and automatic digitization. By finding the period bands for which the signal-to-noise ratio in digitized accelerograms is greater than one, dependence of cut-off periods for accelerogram data processing is presented for amplitude scaling in terms of: (1) Earthquake magnitude and epicentral distance; and (2) modified mercalli intensity at the recording site.
