Non-linear signal processor

摘要

An image is sampled at a given sampling frequency. For each original sample at least one additional sample delayed relative to the first sample is generated (12, 14, 16). The original samples are non-linearly processed (18) and the additional samples are non-linearly processed (20) independently of the processing (18) of the original samples. The output signals from the two processing stages are downsampled (22) back to the original sampling frequency and are metered if required for correcting the overall amplitude and phase vs. frequency characteristic.
