چکیده
In a growing number of applications, there is need to digitize signals whose spectral characteristics are challenging for traditional Analog-to-Digital Converters (ADCs). Examples, among others, include systems where the ADC must acquire at once very wide but sparsely and dynamically occupied bandwidth supporting diverse services, as well signal interest subject strong narrowband co-channel interference. such scenarios, resolution requirements can be prohibitively high. As an alternative, recently proposed modulo-ADC architecture in principle require dramatically fewer bits conversation obtain target fidelity, requires that information about spectrum known explicitly taken into account by analog digital processing converter, which frequently impractical. To address this limitation, we develop blind version no knowledge without sacrificing performance. particular, it features automatic modulo-level adjustment fully adaptive modulo unwrapping mechanism, allowing asymptotically match unknown input signal. addition detailed analysis, simulations demonstrate attractive performance representative settings.

Analog to Digital Conversion
1 ADC TYPES Analog-to-Digital Converters (ADCs) transform an analog voltage to a binary number (a series of 1’s and 0’s), and then eventually to a digital number (base 10) for reading on a meter, monitor, or chart. The number of binary digits (bits) that represents the digital number determines the ADC resolution. However, the digital number is only an approximation of the true value of the ana...
متن کاملPhotonic Analog-to-Digital Conversion
280 INTRODUCTION Accurate collection and processing of electromagnetic information is critical to a wide variety of applications. Present day RF and microwave sensor systems must cover many frequency bands, detect and identify a large range of signal powers, and analyze the signal information on an ever-decreasing time scale. Simultaneously achieving these attributes typically requires multiple...

This paper studies encoding/decoding function of artificial spiking neurons. First, we investigate basic characteristics of spiketrains of the neurons and fix parameter value that can minimize variation of spike-train length for initial value. Second we consider analog-to-digital encoding based upon spike-interval modulation that is suitable for simple and stable signal detection. Third we pres...
