ABSTRACT

The paper gives an automated procedure to design rational decimation compression systems that resample two-dimensional bandpass signals at their Nyquist rates. The procedure takes a sketch of the passband in the frequency domain, circumscribes it with a parallelogram, and linearly maps the parallelogram onto one period of the frequency domain. Thus, the compression system only has linear components.
