A computer system has been developed for data processing of time-series records, specially strong-motion accelerograms and response time-history quantities measured during dynamic tests. The flexibility of the system allows the user to invoke several routines to perform time and frequency-domain operations to the record, such as those commonly used in strong-motion data processing. A simplified procedure for strong-motion data processing is formulated using this system. Improvements on the performance of the Ormsby filter by using a Kaiser window are discussed. Comparison of results for a Peruvian record obtained by the USGS procedure and the proposed scheme, which includes some new developments, showed marked differences. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
