it is necessary to have a table available that lists the ASCII code characters and their corresponding binary representation. Table entries are typically shown in matrix form and can be readily found from sources available electronically. Below, use is made of table entries to decode the first four horizontal entries above.
ASCII Binary Alphanumeric Character
1010100 T
1101000 h
1101001 i
1110011 s
The sequence of 33 binary characters is decoded as (written in the same way that the binary input is presented). Note that the binary 0100000 corresponds to space so that every time that this entry appears, there is space in the text, as shown below.
T h i s
i m e -
n g p
i s
c o n s
r o b 1
