  • In many scientific problems it is necessary to compute the Fourier transform (FT) of a function or measured response that rises quickly then decays slowly with increasing abscissa (independent parameter) value (an 'inverse ramp'). In such cases, it is desirable to derive the function, or sample the response, with a small abscissa interval during the rise, but then increase the interval with increasing abscissa value. Various approximate techniques have previously been presented to accomplish… CONTINUE READING
