✦ Synopsis

The primary aim of this paper is to bring to the attention of shock and vibration engineers the advantages of using digital filters for processing transient response signals. Specifically, the development of reliable high pass digital filters to remove the low frequency components in the acquired acceleration signals so as to obtain valid velocity and displacement-time records, is presented. It is concluded that the non-recursive filters are well suited for mechanical engineering transient response applications. The viability of the non-recursive digital filters for the intended application is established with the use of acceleration signals obtained from a laboratory shock test. Also as a part of this investigation, a set of user-friendly, computer programs for filter design and filtering are developed and implemented.
