Systems and methods for performing analog-to-digital conversion across multiple, spatially separated stages

A system for multiplexing a plurality of analog signals, the system comprising:

• an analog signal receiver comprising a plurality of channels each adapted to obtain an analog signal, and wherein each channel is associated with a channel identifier (chn);
• a signal processor comprising an asynchronous sigma-delta modulator and adapted to perform asynchronous sigma-delta modulation on each of the plurality of analog signals, thereby generating a plurality of quantized time domain signals based on the plurality of analog signals, wherein each quantized time domain signal comprises one or more edge timing events (tn), an edge timing event relating to a signal edge within the quantized time domain signal;
• and
• a multiplexer adapted to multiplex, in an asynchronous manner, the plurality of time domain signals-based on the one or more edge timing events of each signal and the channel identifier, thereby generating a multiplexed signal in which edge timing events are associated with channel identifiers.
