Classification: CPC H | IPC H

Claim 0:
1. A method of transmitting an input analog signal over a digital optical link, comprising the steps of:
digitizing the input analog signal into digitized sequence within a target bandwidth of the digital optical link using a delta-sigma analog-to-digital converter (ADC);
applying a noise transfer function (NTF) to the digitized sequence to generate a digitized output signal that is substantially separated, in the frequency domain, from quantization noise of the digitized sequence; and
transmitting the digitized output signal to a remote receiving unit in operable communication with the digital optical link,
wherein the NTF of the delta-sigma ADC corresponds to a filter of the remote receiving unit, such that the remote receiving unit is enabled to, upon receipt of the transmitted digitized output signal, retrieve from the digitized output signal a second analog signal that is substantially similar to the input analog signal within the target bandwidth.
