Patent attributes
A system for analog-to-digital signal conversion featuring compressed sensing analog-to-digital converter systems. An analog signal is connected to a time encoder having a pulse frequency. The analog signal frequency is higher than the pulse frequency. The time encoder is configured to generate an excitation vector including a plurality of projection values of the analog signal into a plurality of testing basis functions, and a plurality of known basis functions. The output of the time encoder is connected to an input of a pulse domain demultiplexer, and the pulse domain demultiplexer is connected to the pulse-to-asynchronous digital converter in a predetermined sequence. The pulse-to-asynchronous digital converter is connected to the asynchronous-digital-to-synchronous digital converter in a predetermined sequence. The asynchronous-digital-to-synchronous digital converter is connected a digital signal processor configured to output an estimate of the analog signal. Methods to make the foregoing structure are also described.
