Abstract

The paper deals with the experimental comparison of two models for Analog-to-Information Converters (AICs). In particular, a linear model in the time domain and a linear model in the frequency domain have been considered and evaluated for the Random Demodulator AIC architecture. The aim of the present paper is (i) to evaluate the error introduced by both the AIC models, such to determine what best matches the actual implementation, and (ii) to determine the possible error in reconstructing the waveform due to the model.

Keywords

Analog-to-Information Converter, Compressive Sampling, Random Demodulator, subNyquist Sampling.
