A system for performing real time quantization and analog/digital conversion of an analog waveform operating with analog input signals over one gigahertz bandwidth is realized by utilizing a CRT type device in which the electron beam is deflected by the analog input waveform. The deflected electron beam strikes a fast phosphor screen and an externally positioned target consisting of light sensitive elements arranged in a discrete pattern detects and quantizes the signal. The output of the detectors feed an encoder resulting in a binary digital output waveform. The device accepts both unipolar and bipolar video waveform and has parallel output channels such that further circuitry to be employed can operate with reduced bandwidths.

High speed real time quantizer and analog/digital converter

A real time data rate quantizer and analog-to-digital converter system employs an electron beam which is deflected by an analog input waveform. The deflected electron beam strikes a mosaic target in which electron beam sensitive elements detect and quantize the signal. The outputs of the detectors feed an encoder resulting in a binary digital output waveform.
