Abstract:
1. A method that reconstructs a non-uniformly sampled analog signal, comprising: sampling a signal, with an equidistant sample period, by at least one of an analog-digital converter or a time interleaved analog-digital converter; determining a quantized non-uniformly sampled signal comprising the sampled signal with an amplitude error between the signal, and the non-uniformly sampled signal; minimizing the amplitude error by determining a reconstructed amplitude error based on a time offset and the non-uniformly sampled signal, where determining a reconstructed amplitude error comprises: delaying the non-uniformly sampled signal by a delay time needed to reconstruct the amplitude error; subtracting the reconstructed amplitude error from the non-uniformly sampled signal to form a reconstructed non-uniformly sampled signal; and outputting the reconstructed non-uniformly sampled signal.
