Embodiment Construction

[0026] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0027] to combine figure 1 and figure 2 ,exist figure 1 In the extraction application of narrow pulse display, the extraction is performed at equal intervals, and the sampling points are marked as circles in the figure, then the positive pulse width information of the pulse will be lost, and the information of the signal cannot be fed back correctly, resulting in extraction errors. This error may exist as long as the sampling interval is greater than the positive pulse width. In view of the above situation, if the positive peak detection process is adopted for the extracted data segment, the change phenomenon of the pulse signal will not be lost, and will be detected and preserved. The sampling points marked by the two circles in the figure are replaced by the sampling points marked by the corresponding triangles. , the...

Abstract

The invention provides a distortionless extraction judgment method for high speed pulse sampling data and belongs to the field of digital signal processing. The method comprises a fundamental principle of carrying out judgment analysis according to variation characteristics of relatively steep edges of pulse signals, carrying out extraction interval pre-judgment on the pulse signals according to athought of automatically judging and adjusting control parameters based on signal hop, and realizing distortionless adaptive processing of extraction processing of the pulse signals. According to themethod, judgment processing can be carried out through utilization of a field-programmable gate array; speed is fast; a former process of collecting data, transmitting the data to an upper computer CPU for processing through utilization of a bus, and feeding back the data to a lower side for extraction control can be avoided; adaptive judgment processing of front-end pulse signal distortionless extraction is realized; and processing efficiency is improved. Through distortionless judgment processing, an error resulting from the fact that signal useful information is lost due to excessive signal extraction is avoided, and signal processing timeliness and effectiveness are ensured.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a method for extracting and discriminating high-speed pulse sampling data without distortion. Background technique [0002] Extraction is a method often used in data analysis, especially in the field of high-speed acquisition. Due to the high sampling rate, a large amount of data is often generated, but in many actual analysis, processing, and applications, it is not possible to directly process so much data. , but some useful data information in the data must be extracted first, and then processed in a targeted manner, so as to meet the real-time and effectiveness requirements of signal analysis and processing. For example, in the waveform display of high-speed acquisition, if the acquisition time is long, the amount of data will be large. For the waveform display, if all the data are drawn and displayed, first the bus transmission will take a certain amount of time, and...
