摘要： Analog-to-digital conversion is performed on a received an analog input signal. A supplemental analog signal is generated. The supplemental analog signal is characterized by an amplitude sufficient to trigger each voltage threshold in a non-uniform sampling analog- to-digital converter. The received analog input signal and the generated supplemental signal are mixed. The non-uniform sampling analog-to-digital converter converts the mixed analog signal, producing a series of {amplitude, time} tuples representative of the mixed signal. The series of {amplitude, time} tuples are interpolated to form a series of samples periodic in time representative of the mixed signal. The supplemental signal is removed from the interpolated series.
