For the following clock time (assume the colon is a constant) 12:01, translate into BCD and ASCII
To translate the clock time 12:01 into BCD (Binary-Coded Decimal) and ASCII, we first need to understand the representation of BCD and ASCII.
BCD is a way of representing decimal digits (0-9) using binary numbers. Each decimal digit is represented by 4 bits, also known as a nibble, in BCD format.
ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents characters as numeric codes. It includes a set of printable and non-printable characters.
Let's start with the BCD representation:
1. Convert the hour and minute digits into BCD.
- For the hour digit '1', the BCD representation is '0001'.
- For the hour digit '2', the BCD representation is '0010'.
- For the minute digit '0', the BCD representation is '0000'.
- For the minute digit '1', the BCD representation is '0001'.
So, the BCD representation of the clock time 12:01 is '0001 0010 : 0000 0001'.
Now let's move on to the ASCII representation:
1. Convert each BCD digit into its equivalent ASCII character.
- For '0001', the ASCII character is '1'.
- For '0010', the ASCII character is '2'.
- For '0000', the ASCII character is '0'.
- For '0001', the ASCII character is '1'.
Therefore, the ASCII representation of the clock time 12:01 is '1 2 : 0 1'.
To summarize:
BCD representation: '0001 0010 : 0000 0001'
ASCII representation: '1 2 : 0 1'
