OK I got your point.BUT another confusion.can more than one symbol be inserted in the transmitted word? Anupam Ghosh,Bengal Engg and Sc Uni,MtechIT,2006-09,India 26 Aug 2009 13:36

Any (but only one) symbol 0 is replaced by 1.
Any (but only one) symbol is removed.
A symbol (0 or 1) is inserted at any position. ......(but only one) is missing here in this statement

Re: OK I got your point.BUT another confusion.can more than one symbol be inserted in the transmitted word? gvsmirnov 22 Sep 2009 20:50

Such use of indefinite article "A" implies "one".
so, no, only one symbol is inserted.
