摘要： An opto-electronic A/D converter includes a tunable laser (10) for wavelength modulating a narrowband coherent electromagnetic beam by the amplitude of the analog signal. A grating (12) transforms the wavelength modulated beam into a corresponding angularly modulated beam. A set of kinoforms (14) diffract the angularly modulated beam into a bundle of diffracted beams. Detectors (18, 20) determine the digital signal by repeatedly sampling the spatial power distribution of the diffracted beams.

摘要： Un circuit discrimateur analogique à haute vitesse utilise un tube à rayons cathodiques (21) et comporte une pluralité d'éléments cibles (43, 45) disposés en cercle, et dont le faisceau à électrons balaie de façon répétée les éléments cibles disposés en cercle. L'amplitude du signal analogique destiné à être échantillonné est appliquée à une grille (41) du tube à rayons cathodiques afin de moduler l'intensité du faisceau d'électrons avant qu'il ne frappe les conducteurs. Les électrons qui frappent les élements cibles créent une tension détectable proportionnelle à l'amplitude de la tension analogique aux différents moments où le faisceau d'électrons frappe les différents éléments cibles. Cette sortie peut encore être codée numériquement par un ou plusieurs convertisseurs de signaux analogiques en signaux numériques.

摘要： A system and method for converting an analog voltage signal to a digital representation at high speeds, known as an analog to digital converter (A/D converter), is provided. The invention teaches an N-bit A/D converter, made by N superconducting, preferably HTC, transmission lines. The N lines are arranged adjacently and in parallel with each other. On each line 2N-1 JJs are imbedded in series. The JJs form a matrix over the configuration of the N superconducting transmission lines in such a manner that across the lines the JJs give N digit binary numbers, while in the length direction these N digit binary numbers fall in numerical order. A scanning electron beam is made to impinge on this arrangement. The beam is scanned across the lines at a high frequency, while it is deflected by the applied voltage signal along the direction of the lines. The beam generates a voltage step on any one of the N lines on condition of hitting any one of the JJs. In this manner upon each cross-scanning of the beam, an N-bit step voltage pattern is generated on the lines. This pattern is the direct digital readout of the input voltage signal.

摘要： A high speed analog sampler using a CRT (21) having a number of target elements (43, 45) arranged in a circle with the electron beam being repetitively scanned over the target elements in a circle. The amplitude of the analog signal to be sampled is applied to a grid (41) of the CRT to modulate the intensity of the electron beam prior to its striking the conductors. Electrons striking the target elements create a detectable voltage proportional to the amplitude of the analog voltage at the various intervals in time that the electron beam struck the various target elements. This output can further be digitized by one or more analog-to-digital converters.

摘要： In an analogue-to-digital converter based on the principle of deflection of an electron beam striking a target plate, the number of diodes in the target plate is doubled and covered with a metal pattern in a manner such that besides the original digital signal the complementary digital signal is now also available. Thus, a faster conversion can be achieved. The metal pattern can also be extended so that the extreme values of the voltage to be converted are detected in a simple manner.
