- Abstract:
- In this paper we will present a simple and cost effective, yet accurate, setup for measuring the amplitude distribution of a signal and its probability density function (pdf ). From these, it will be shown how to measure and model linear and memoryless nonlinear errors using both a power and an orthogonal series representation of the distorted signal, and how to use this knowledge to improve the resolution of an ADC characterization. Finally, we will give an usage application, with experimental results, in which the nonlinearities of a low grade stimulus are ‘subtracted’ in the histogram method for the characterization of ADCs.
