This paper proposes a new algorithm which draws on the strength of the 4-parameter estimation algorithm and a modified FFT method and can easily automate the process without worrying about various constraints imposed by the previously published algorithms.Abstract:
One of the most important performance indicators of an A/D
converter is the effective bit. The effective bit of an A/D converter
measures the average power of the noise generated in the process of
analog to digital conversion. Three major methods for estimating A/D
effective bit are minimum mean square error sine fitting algorithm,
4-parameter estimation algorithm, and the FFT method. Each method has
its own strength and weakness. In this paper we propose a new algorithm
which draws on the strength of the 4-parameter estimation algorithm and
a modified FFT method. With this new algorithm, user can easily automate
the process without worrying about various constraints imposed by the
previously published algorithms. Extensive simulations have shown that
the new algorithm is fast, robust, and gives accurate resultsread more

Sinewave parameter estimation algorithm with application to waveform digitizer effective bits measurement
Yih-Chyun Jenq,P.B. Crosby +1 more
TL;DR: A high-performance algorithm to estimate the four parameters (amplitude, DC offset, frequency and phase) of a sine wave from a sampled data record is presented and results indicate that the method gives excellent estimates of the true resolution of the simulated ideal digitizer.
