Abstract
This Information Circular describes a comprehensive digital signal processing system, developed by the Bureau of Mines, called BoMSPS. Operations such as gain control, muting, normalization, polarity change, randomization, scaling, shifting, stacking, smoothing, and windowing account for the basic time-domain operations available. Higher order time-domain enhancement capabilities involve convolution, deconvolution, autocorrelation, and cross correlation. Frequency-domain attributes such as the real transform, imaginary transform, relative amplitude, and power and phase spectra can be determined. Frequency-domain filter capabilities permit the investigator to employ a half-sine or cosine window, notch band- pass, or high-cut or low-cut filter, while interactively defining the rolloff of either a linear or cosine taper. Calculation of related trace attributes such as quadrature (hilbert transform), instantaneous amplitude, and instantaneous phase is also available. This program should be a welcome addition for those mining and environmental geophysicists, researchers, and engineers interested in processing signals.
