Abstract

The invention is applicable to the field of signal detection, and provides a pulse amplitude analyzing circuit and a pulse amplitude analyzer. The pulse amplitude analyzing circuit comprises a charging unit, a signal discriminating unit, a control unit and a resetting unit. By using the pulse amplitude analyzing circuit and the pulse amplitude analyzer, through counting nuclear pulse signals through the signal discriminating unit, recording the peak value information of the nuclear pulse signals, controlling discharge by the control unit and outputting single-channel output signals self-adapting to the widths of the nuclear pulse signals, the carrying of the physical quantities with the widths of the nuclear pulse signals in the single-channel output signals is achieved; the information extraction quantity of the pulse amplitude analyzer is increased; and the application of the pulse amplitude analyzer is extended.

Description

technical field [0001] The invention belongs to the field of signal detection, in particular to a pulse amplitude analysis circuit and a pulse amplitude analyzer. Background technique [0002] The nuclear physics signal is a series of random pulse signals, and each pulse represents a physical event. For example, when a ray is detected, a nuclear pulse is generated every time a ray is detected. The pulse width includes the time information of the ray, and the pulse amplitude includes The energy information of the ray. [0003] The current pulse amplitude analyzer screens the nuclear pulse signal, and usually converts the nuclear pulse signal into a standard digital signal. In general, the single-channel output signal is a standard digital signal with the same width, which can only be used for The nuclear pulse counting cannot carry the physical quantity represented by the pulse width.
