Abstract
In a first embodiment, a data transmitter according to the invention includes a digital-to-analog converter adapted to receive an input signal and produce a plurality of images therefrom, each image being displaced from the other images in frequency, and a compensation filter adapted to compensate at least one of the plurality of images to adjust for a loss inherent in the digital-to-analog converter. In an alternative embodiment, a receiver includes an analog-to-digital converter adapted to receive a line signal comprising a plurality of frequency diverse images, and to produce a sampled signal representative of a single image therefrom. In another alternative embodiment, a method of transmitting a signal includes the steps of creating a plurality of images of a main signal, compensating at least one of the images, and outputting the images. In yet another embodiment, a method of receiving a signal includes the steps of receiving a plurality of images, and processing the plurality of images so that an uncorrupted portion of one image compensates for a corrupted portion of another image.
