Automatic Control Technique Research on Periodic Narrow Pulse Signal Precision Measurement

It is comparatively difficult to measure precisely the narrow pulse signal of less than 1mus by means of routine methods, and it is costly by using express acquisition equipment. Precision measurement with integration method for the periodic narrow pulse signal described in this paper is just satisfactory. With energy measurement of a certain beam as one example, based on integration circuit principle, this paper gives a detailed analysis and discussion on design of amplifying circuit, error resources of measurement and processing. This paper also explains shortcomings of the integration circuit and describes in a detail principle and constitutes of the envelope-forming circuit.
