5. Defination of Encoder
The encoder is a combinational circuit that performs the reverse operation
of the decoder. The encoder has a maximum of 2n inputs and n outputs.
The simplest encoder is a 2n-to-n binary encoder
One of 2n inputs = 1
Output is an n-bit binary number

6. Encoder – What is it?
An encoder is a:
Device
Circuit
Transducer
Software Program
Algorithm
Person
that converts information from one format to another

8. LINEAR ENCODER :
A linear encoder is a sensor,
with a scale that encodes
position. The sensor convert
the encoded position into
an Analog signal analog or
digital signa

20. The Digital Encoder
Digital Encoder more commonly called a Binary
Encoder takes ALL its data inputs one at a time
and then converts them into a single encoded
output.
So we can say that a binary encoder, is a multi-
input combinational logic circuit that converts
logic level "1" data at its inputs into an equivalent
binary code at its output.
22. The Digital Encoder
Generally, digital encoders produce outputs
of 2-bit, 3-bit or 4-bit codes depending upon
the number of data input lines. An "n-bit"
binary encoder has 2n input lines and n-bit
output lines with common types that include
4-to-2, 8-to-3 and 16-to-4 line
configurations.
