| Abstract: | This paper is the second paper about the theory and application of amplitude non-uniformly sampled signals.In this paper,at first we analyze the effect of the offset error in paper 1] on the input signal's spectra,then explain the principle of increasing the amplitude resolution,and derive the additional signal spectra representation with sinusoid input.We present two methods to improve the system amplitude resolution.At last,computer simulation to obtain the relation curve between the system ENOB and the input signal's frequency is given. |

| Keywords: | offset error amplitude resolution signal-to-noise ratio |
