Question
Chapter 4, Problem 4.3QAP
Interpretation Introduction
Interpretation:
To decide out of binary and BCD which system of encoding decimal numbers is more efficient based on number of bits taken for encoding and the reason should be determined due to which less efficient coding scheme is very useful.
Concept introduction
BCD:
A decimal number can be converted into its BCD equivalent by replacing each digit of given decimal number into its corresponding four-bit binary equivalent.
Binary:
A decimal number can be converted into its binary equivalent by continually dividing it by 2 and keeping track of the remainder.
