This article discusses a new approach to size an analog-to-digital converter (ADC) for the simultaneous acquisition of two signals. It allows evaluating the resolution, which fulfills a certain dynamic range (DR) in the case of multiple signals with different powers. Experimental results with software-defined radios (SDRs) confirm our simulations. It shows that we are able to acquire an intra-quantum signal due to the contribution of a stronger transmission, which makes it cross the quantization levels. Some insights about another way to exceed the theoretical DR with the inherent noise in electrical systems are also provided. Thus, we propose to give the ADC required resolution to detect an intra-quantum signal when simultaneously received with a stronger one which, to the best of our knowledge, has never been thoroughly studied.

内量子信号数字化的 ADC 分辨率要求

本文讨论了一种为同时采集两个信号来确定模数转换器 (ADC) 大小的新方法。它允许评估分辨率，在具有不同功率的多个信号的情况下满足一定的动态范围 (DR)。软件定义无线电 (SDR) 的实验结果证实了我们的模拟。它表明，由于更强传输的贡献，我们能够获取内部量子信号，这使得它跨越量化级别。还提供了一些关于用电气系统中的固有噪声超过理论 DR 的另一种方法的见解。因此，我们建议为 ADC 提供所需的分辨率，以便在与更强的信号同时接收时检测内部量子信号，据我们所知，该信号从未被彻底研究过。
