Analog to digital converter for audio and video data and all electronic uses has subtracter integrator comparator and digitizer components

摘要

An analog-to-digital converter comprises a subtracter (1) producing a difference signal from the analog input and an analog approximation signal, an integrator (30) for this signal, a comparator (40,50) to determine if this is in a given relation to a threshold and a device (70,80) to determine a dependent digital bit. Independent claims are also included for the following: (a) a converting process for the above;and (b) an operational process
