The report mainly discusses, compares, and derives one new and improved and two popular shock spectrum computation methods. The new one is a single recursive equation method that approximates the acceleration as a straight line between the digitized values. The new method is easily derived without recourse to Z Transform theory and, thus, should contribute to improved understanding of the computations. A new source of low frequency error common to all of the calculation methods was found, and empirical testing of the coefficients was used to establish digitizing rules to avoid the error. A FORTRAN listing of a program using the new method is given in an appendix.The report mainly discusses, compares, and derives one new and improved and two popular shock spectrum computation methods.
