| Zusammenfassung: | The utility model discloses a gamma-ray discriminator, comprising a signal amplifier circuit, a delay circuit, a peak value retaining circuit, a time sampling circuit, a coincidence gate circuit, a counting circuit and a preset register. The utility model is characterized in that the signal is screened in digital manner according to the time range affirmed by the time sampling circuit through a percent and b percent of the peak value of the signal rising edge and the falling edge. The utility model has the advantages of high precision and simple circuit. |
