Systems and methods for asynchronous data communication in noisy environments

Abstract

Systems and methods for asynchronous data communication are disclosed. The system includes one or more peripheral devices, a processing device, and one or more communication channels. Each peripheral device includes a peripheral clock and a quantizer. The processing device is remotely located from each peripheral device and includes a processor clock that is asynchronous with at least one peripheral clock, an analog continuous time filter, and an analog-to-digital converter. The analog continuous time filter filters 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 has a filter bandwidth corresponding to a signal bandwidth of one or more analog time varying signals represented by the one or more quantized signals. The analog-to-digital converter generates one or more converted signals by sampling the one or more filtered signals based on a processor clock signal.
