ABSTRACT:
A pulse shaping circuit for use in a radiation detector. This circuit is adapted for x-ray spectroscopy. The pulse shaping circuit comprises a circuit for converting the output signal from the radiation detector into a step-function waveform, a pseudo-Gaussian filter consisting of a plurality of cascaded filter circuits, an adder circuit, and a gated integrator for integrating the output from the adder circuit. The adder circuit proportionally adds the outputs of each of the plurality of filter circuits in a predetermined manner and sums them up. The pulse shaping circuit achieves a high counting rate and a high resolution.
