    摘要: A signal processing system allows reconstruction of a non-uniformly sampled analog signal including sampling an analog signal at a sampling period of resulting in a quantized non-uniformly sampled signal. The non-uniformly sampled signal includes a sampled signal and an amplitude error between a signal sampled with the equidistant sample period and the non-uniformly sampled signal. A reconstructed amplitude error is determined through the time offset and the non-uniformly sampled signal, and is subtracted from the non-uniformly sampled signal. The signal processing system may be implemented in an electrocardiogram monitoring device or a mobile phone device.

    摘要: An arrangement for a time interleaved analog-to-digital converter that converts an signal to a digital signal and has a converter array with a plurality of analog-to-digital converters arranged in a fixed sequence in parallel with one another and can be operated with staggered timing with respect to one another is disclosed. The arrangement has a connection network which, for the purposes of actuation with staggered timing, generates in each case one control signal for an individual analog-to-digital converter in each case, with the connection network predefining the time sequence with which the control signals actuate the individual analog-to-digital converters in such a way that owing to this sequence of the control signals and thus the sequence of the actuated individual analog-to-digital converters there is at least a reduction in an interference spectrum in the spectrum of the input and/or output signal. A sorting method for operating this analog-to-digital converter is also disclosed.
