This paper presents a digital method for the poles identification of an analog system consisting of a preamplifier and a shaping filter in the digital spectroscopy.Based on this method,the result of the simulation of the analog and digital system is modeled in the Matlab and Simulink platform.The influence of noise,the ghost zero and some realization problem is also discussed.The algorithm is based on SVD of the Hankel.With the advantage of accuracy,operating in real-time,numerical stability and requiring no initialization,the method is widely used.
