A data translation system () for performing a non-linear data translation on a digitized AC signal is provided. The non-linear data translation system () includes an input for receiving the digitized AC signal, an output for outputting a non-linearly translated signal, and a processing system () coupled to the input and to the output. The processing system () is configured to receive the digitized AC signal, non-linearly translate the digitized AC signal using a predetermined transfer function to create the non-linearly translated signal, and transfer the non-linearly translated signal to the output.

A signal processor () is provided. The signal processor () is configured to receive a first analog signal and convert the first analog signal into a digital signal. The digital signal is transmitted across an electrical barrier and converted into a scaled pulse width modulation signal. The scaled pulse width modulation signal is then converted into a scaled second analog signal, which is output by the signal processor ().

A delta-sigma modulator () including a dithering capability for eliminating idle tones is provided according to the invention. The delta-sigma modulator () includes a bitstream converter () configured to generate a digital signal output substantially corresponding to an analog signal input, a periodicity detector () coupled to the bitstream converter () and configured to detect periodicity in the digital signal output, and a dithering sequence generator () connected to and activated by the periodicity detector (). The dithering sequence generator () generates a dithering sequence. The delta-sigma modulator () further includes a pulse-width modulation (PWM) generator () coupled to the dithering sequence generator () and receiving the dithering sequence. The PWM generator () modulates the dithering sequence onto the analog signal input of the delta-sigma modulator () as a dithering signal.
