ABSTRACT:
Methods and structures are provided for generating a digital display signal in response to an analog display signal whose amplitude varies at a pixel rate and in response to a synchronization signal that defines spatial order for the analog display signal. The structures include a transform generator for providing a Fourier transform of the digital display signal and a transform analyzer which generates frequency and phase control signals in respective response to the frequency of an error spectral component and amplitudes of image spectral components in the transform. The frequency and control signals are applied to respectively adjust the sample rate of the sample clock and alter the phase of the sample clock.
