Abstract

To make it possible to achieve a more high-speed operation while suppressing increase in power consumption.SOLUTION: An Analog-Digital converter comprises: a plurality of signal lines that transmits a source signal with an electromagnetic continuous wave as the source signal; a plurality of phase modulators that respectively modulates respective phases of the plurality of source signals in responce to an input signal; a multiplexor that has an input unit inputting a plurality of phase modulation signals having the phase modulated by the phase modulator, a multiplexing unit spatially and continuously multiplexing the plurality of phase modulation signals to be input to the input unit and causing the phase modulation signal a non-linear signal conversion, and one or more output units outputting a signal having the signal converted; and one or more binarizers that binarize respectively the signal output from the multiplexor at an arbitrary value.SELECTED DRAWING: Figure 1

Claims

1. An electromagnetic continuous wave is used as the source signal, and a plurality of signal lines transmit the source signal, Multiple phase modulators, each modulating the phase of each of the multiple source signals according to the input signal, A multiplexer having an input section that receives multiple phase-modulated signals whose phases have been modulated by multiple phase modulators, a multiplexing section that spatially and continuously combines the multiple phase-modulated signals input to the input section, causing the generated interference light to further interfere with other interference light, and repeating the interference continuously and spatially, thereby causing a nonlinear signal conversion in the phase-modulated signals, and one or more output sections that output the signal converted by the multiplexing section, Each of the following are one or more binarizers that binarize the signal output from the multiplexer at an arbitrary threshold, Equipped with, The aforementioned binarizer outputs random values ​​without any regularity from the analog-to-digital converter.

2. The analog-to-digital converter according to claim 1, wherein the relationship of the phase difference between the plurality of phase-modulated signals input to the multiplexer is set to be different with respect to a second input signal that is different from the first input signal.

3. The analog-to-digital converter according to claim 1, further comprising a code converter that converts a binary code sequence output from the binarizer into any code.

4. The analog-to-digital converter according to claim 1, wherein the multiplexing section includes an object, structure, or mechanism that affects the signal during the propagation process of the signal within the multiplexing section.

5. The analog-to-digital converter according to claim 4, wherein the effect includes at least one of refraction, reflection, diffraction, scattering, and deceleration of the signal within the multiplexer.
