what metric unit is used to describe the mass of an object?
kilogram
the metric system was developed during the french revolution to replace the various measures previously used in france. the metre (sometimes spelled "meter" in american english) is the unit of length in the metric system and was originally based on the dimensions of the earth, as far as it could be measured at the time. the litre (american english "liter"), is the unit of volume and was defined as one thousandth of a cubic metre. the metric unit of mass is the kilogram and it was defined as the mass of one litre of water. the metric system was, in the words of french philosopher marquis de condorcet, "for all people for all time".
introduction to the metric system
there are both hardware (in modems) and software implementations of a viterbi decoder.









































section::::hardware implementation.









































a hardware viterbi decoder for basic (not punctured) code usually consists of the following major blocks:









































bullet::::- branch metric unit (bmu)









































bullet::::- path metric unit (pmu)









































bullet::::- traceback unit (tbu)









































section::::hardware implementation.:branch metric unit (bmu).









































a branch metric unit's function is to calculate "branch metrics", which are normed distances between every possible symbol in the code alphabet, and the received symbol.
