Precision of sinewave amplitude estimation in the presence of additive noise and quantization error

Francisco André Corrêa Alegria

   This research paper delves into a comprehensive investigation concerning the impact of additive noise and quantization error on the precision of amplitude, offset, and phase estimates of a sine wave fitted to a set of data points acquired by a waveform digitizer. Simulation results are used to validate the expressions presented.

Keywords: sinewave, fitting, uncertainty, analog-to-digital conversion, ADC, quantization
