Webanalysis procedure be used. The Smallwood algorithm is the obvious choice. Before the time history is passed to the SRS processor, any low-frequency offsets must be removed. This operation, called preprocessing, is done in two steps: 1. A block of data just before the shock is averaged and the result is subtracted from the whole time history. 2. WebDamping is typically fixed at a constant value, such as 5%, which is equivalent to an amplification factor of Q=10.
