ABSTRACT:
A method and apparatus is disclosed for decoding a redundantly coded digital signal wherein each information character is coded with a plurality of signal elements. Each of the signal elements is sampled by an analog to digital converter (110) and the resulting sample value is transmitted to an adder (114). The sampled value is added to an accumulated sum which is received from a storage circuit (128). The sum of the sampled value and the accumulated sum is transmitted through a selector switch (120) to both a decision circuit (126) and the storage circuit (128). After the last of the redundantly coded signal elements is sampled and the sampled values included within the accumulation sum, the state of the information character is determined by the decision circuit (126). Switch (120) then enters a null data set to reset the accumulated sum to zero for processing the next group of redundantly coded signal elements.
