Digital Electronics - Number Systems and Codes - Discussion

Correct Explanation available here:

Step 1: Divide the code into 7-bits each

(1010011) (1010100) (1010101) (1000100) (1011001)
(0100000) (1001000) (1000001) (1010010) (1000100)

Step 2: Convert binary data to decimal individually

Step 3: (83) (84) (85) (68) (89) (32) (72) (65) (82) (68)

Step 4: Substitute characters of ASCII values

Example:-
65-A
66-B
67-C
....
....
90-Z
32-blank, etc.

i.e code converted into text as STUDY HARD

Note:- If given data is not consisting 7 multiples of bits then append 0's to MSB i.e left hand side of data.

Also you should remember that characters case i.e upper or lower.

Hey but according to ASCII table 53 means U, how come here they have taken S for 53 !?

Hey @deepika it is simple yaar. Take left side eight digits.

Eg: 01010011 this represent 53. That is the hex dec 53.

I can't understand this explanation please explain.

010100111010100101010110001001011001
01000001001000100000110100101000100
Add 0 to LHS to make it a multiplier of 4
now... 0101 0011=53..that is the hexadecimal of 'S'
Likewise 54 of 'T'
55 of 'U'
.
.
.
20 of space
Hence solved..

Please any one explain me, I cant understand these.
