AbstractA number of operations for processing deterministic signals obtained from measurements of structural dynamics have been carried out in the frequency domain. They include instrument correction including angular motion, integration and differentiation, baseline adjustment, and filtering. A survey of computational considerations includes aliasing, the Fast Fourier Transform (FFT), the transformation of long records, wrap-around, and the leakage phenomenon. Numerical examples illustrate baseline adjustment, leakage, and wrap- around.
