Abstract
This paper describes the use of digital-computer techniques to improve the quality and reduce the cost of transient-data processing and transient-test control. The reciprocal properties of the discrete Fourier integral transform, coupled with the use of modern digital-computing algorithms, have been used to provide transient-data-distortion compensation, permit the calibration of accelerometers and pressure pickups by transient excitation, and to provide transient-waveform control using electromagnetic exciters. The basic principles of the techniques used are explained, and examples of their applications shown.
