ABSTRACT:
A programmable circuit for sampling an IR signal is responsive to a clock signal and a plurality of programmable factors which establish the characteristics of the sampling pattern. The circuit provides successive groups of samples whose resolution, phase and periodicity are established by the programmable factors such that IR signals characterized by different formats may be conveniently accommodated by the same hardware.
