摘要： A method for generating a digital signal representative of the pairing error between the channels of an analog digital conversion system with time interleaving, and a method for suppressing the errors thus calculated and an analog digital conversion system with time interleaving using same. The method comprises determining a spectrum (11-12) of the digital signal as a function of a frequency response of the analog digital conversion system with time interleaving (CAN 10) to at least one analog calibration signal (IC), and generating a “comb” signal whose spectrum is composed of frequency lines kFs/N, where Fs is a sampling frequency and N a number of channels of the analog digital conversion system with time interleaving, and whose amplitude is dependent on the frequency response of the analog digital converter.

摘要： The invention relates to a method for generating a digital signal representative of the pairing error between the channels of an analog digital conversion system with time interleaving, a method for suppressing the errors thus calculated and an analog digital conversion system with time interleaving using same. The present invention proposes a less complex digital solution since it does not require the extraction of the defects of the signal at the output of the converter. It makes it possible to correct the pairing errors by the direct creation of digital signals representative of these errors, and their subtraction from the digitized signal at the output of the conversion system. An object of the invention is a method for generating a digital signal representative of the pairing error between the channels of an analog digital conversion system with time interleaving (CAN 10) comprising an analog digital converter (CAN1, CAN2,...,CANN) on each channel. The said method comprises the determination of the spectrum (11-12) of said digital signal as a function of the frequency response of the analog digital conversion system with time interleaving (CAN 10) to at least one analog calibration signal (IC).
摘要翻译：本发明涉及一种用于产生代表模拟数字转换系统的信道与时间交织之间的配对误差的数字信号的方法，一种用于抑制如此计算的误差的方法和使用其的时间交织的模拟数字转换系统。本发明提出了一种较不复杂的数字解决方案，因为它不需要在转换器的输出处提取信号的缺陷。通过直接创建表示这些错误的数字信号，以及从转换系统的输出端的数字化信号中减去配对误差，可以实现这一点。本发明的目的是一种用于产生代表模拟数字转换系统的通道与时间交错（CAN 10）之间的配对误差的数字信号的方法，包括模拟数字转换器（CAN＆lt; 1＆gt; 每个通道上的CAN _{2 ，...，CAN _{N ）。所述方法包括根据随时间交织（CAN 10）至少一个模拟校准信号（IC）的模拟数字转换系统的频率响应的函数来确定所述数字信号的频谱（11-12）。}}
