Abstract

A method for analog-to-digital conversion of an analog signal includes decomposing the signal in the time domain into intervals, and transforming these intervals one after another using orthogonal functions, the coefficients corresponding to the orthogonal functions being defined and digitized. The transformed signal is then inversely transformed in the digital domain using the digitized coefficients and the same or different orthogonal functions. A high level of performance with respect to bandwidth and resolution may be achieved.
