Systems and methods for asynchronous data communication in noisy environments

A system for asynchronous communication in noisy environments, the system comprising:

• one or more peripheral devices, each peripheral device comprising:
• a peripheral clock for generating a peripheral clock signal;
• and
• a quantizer for generating a quantized signal representing an analog time varying signal at the peripheral device by sampling the analog time varying signal based on the peripheral clock signal, the quantized signal comprising at least two discrete amplitude levels;
• a processing device remotely located from each peripheral device, the processing device comprising:
• a processor clock for generating a processor clock signal, the processor clock signal being asynchronous with at least one peripheral clock signal;
• an analog continuous time filter for filtering one or more quantized signals generated by the one or more peripheral devices to generate one or more filtered signals, the analog continuous time filter having a filter bandwidth corresponding to a signal bandwidth of one or more analog time varying signals represented by the one or more quantized signals;
• and
• an analog-to-digital converter for generating one or more converted signals by sampling the one or more filtered signals based on the processor clock signal, each converted signal representing an interpolation of one of the one or more analog time varying signals that is synchronized with the processor clock signal;
• and
• one or more communication channels for transporting the one or more quantized signals from the one or more peripheral devices to the processing device, each communication channel coupled between at least one peripheral device of the one or more peripheral devices and the processing device.
