Digital Encoder

[edit | edit source]

A digital encoder is a digital device that uses bits to represent information as binary numbers.

Examples

[edit | edit source]

Example 1

[edit | edit source]

Using a two bit binary number we have four 2 bits binary numbers

00
01
10
11

Let

00 --- 0
01 --- 1
10 --- 2
11 --- 3

The decimal numbers from 0 to 3 are encoded as 2 bit binary numbers.

Example 2

[edit | edit source]

Similarly, with a 4 bit binary number we can encode the decimal numbers from 0 to 15 as shown below

0000 --- 0
0001 --- 1
0010 --- 2
0011 --- 3
0100 --- 4
0101 --- 5
0110 --- 6
0111 --- 7
1000 --- 8
1001 --- 9
1010 --- 10
1011 --- 11
1100 --- 12
1101 --- 13
1110 --- 14
1111 --- 15
