DISCRIMINATION OF HEART SOUNDS USING CHOAS ANALYSIS IN VARIOUS SUBBANDS

An encoder system and technique is disclosed for providing greater resolution for position indications. The encoder includes multiple small absolute encoders coupled through a fixed gear ratio to provide an increase in the number of positions which may be absolutely resolved by the encoder without a significant increase in the size of the encoder. The resulting configuration produces a size which is the sum of the individual sizes of the multiple encoders but produces a resolution which is proportional to a multiplication of the individual encoder positions. The resulting encoder provides an absolute indication of position without the requirement for knowledge of the previous position or a predetermined rotation prior to position indication.
