Variable Length Coding (that is, assigning a variable length code word with different numbers of bits representing different symbols) will always provide a coding advantage (i.e. the average number of bits/symbol) when compared with a fixed length coding scheme (i.e. all symbols are represented by code words with the same number of bits).Question 4Select one:TrueFalse

Variable-length source codes provide bit savings compared to fixed-length source codes.Group of answer choicesTrueFalse

The average number of bits/symbol is obtained by calculating the sum of all piLi, where pi is the probability of symbol i and Li is the length (in bits) of the code word used to represent symbol i. If we use a fixed length code word (e.g. each symbol is represented by a 4-bit word), then the average number of bits/symbol is independent of the probability distribution.Question 1Select one:TrueFalse
