ABSTRACT:
Signal converter systems are provided with N analog-to-digital converters that respectively respond to N interleaved clock signals which have a common clock frequency and are further provided with a filter network that processes the converters' output digital sequences with a selected filter passband a filter passband that is contained within a single one of Nyquist zones whose widths are one half of the clock frequency and that is positioned to pass information contained in the analog signal. In a system embodiment, the filter network comprises a symmetric systolic finite impulse response filter arranged to define N input ports for reception of the digital sequences.
