WebThis is because you must use the same number system (or data type as you called it) to compare. So you cannot consider only the number of digits (A=18 and B=12). WebThe variable-bit encoding rule would use only one bit 50 percent of the time, two bits 25 percent of the time, and three bits 25 percent of the time. On average it would use 1.75 bits per sample rather than the 2 bits per sample used in the standard code.
