- Abstract:
- The Discrete-Time Convolution Model behavioural approach is proposed for the characterization/empirical modelling of high-performance broad-band A/D channels, designed for the acquisition of signals approaching the microwave field. Thanks to its inherent capability of separately describing all the nonidealities of different nature within the channel, and in particular the non-linear dynamic effects, the method is particularly suitable for the A/D channels of modern high-frequency instrumentation and RF receivers. Experimental results are provided, which validate the analytical formulation of the approach and the related measurement procedures/set-ups for model parameter experimental extraction, for a state-of-the-art, 1-GHz analog bandwidth 1-GSa/s A/D acquisition channel for satellite radar applications.
