In many situations, the theory of signal detectability lacks a connection between the theoretical aspects and the practical implementation of a detector. This condition exists because there are no general techniques for evaluating the detector performance. This report contains a collection of available techniques which have been adapted for the computer evaluation of a large class of detectors. In addition to the classical approximations, the Pearson system of frequency curves is integrated into the computer programs. The Pearson system yields a closedform approximation to the detector performance, based on the moments of the signal and noise distribution functions. Such closed-form approximations enable the user to evaluate the effects of signal-to-noise ratio, detector nonlinearities and filter bandwidth. Author
