Abstract
The use of digital demodulation techniques, or the conversion from analog to digital signal domains before data are demodulated from a radio frequency (RF) carrier, has become increasingly more feasible in recent years as logic circuit speeds have increased. This feasibility has been demonstrated by use in the Dual-Channel (Mu-II) Sequential Ranging System. Further use is contemplated in the telemetry stream, or integrated into the phase-tracking receiver. This article reviews some of the properties which must be considered in the analog-todigital (A-D) converter to be used in these applications. In particular, the loss to be expected with an A-D unit built from current circuitry is calculated.
