ABSTRACT:
In an Omega receiver, for each of the Omega frequencies (10.2 KHz, 11 1/3 KHz, 13.6 KHz), a desired frequency is isolated by selectively sampling received signals at predetermined intervals. The samples are then processed such that samples corresponding to a desired frequency are additive and those corresponding to interferring signals cancel. Processing includes inverting certain samples and combining.
