Pp. Roberts, CALCULATING QUANTIZATION CORRECTION FOR DIGITAL CORRELATORS WITH DIGITAL FRINGE ROTATION, Astronomy & Astrophysics. Supplement series, 126(2), 1997, pp. 379-383
A method for calculating the conversion relationship between measured
digital correlation and true analogue correlation, for digital correla
tors incorporating digital fringe rotation, is presented. Explicit exp
ressions for the efficiency of correlators of this type are derived wh
ich can be used to optimise correlator system parameters. Results are
presented for four correlation schemes in common use.
